Godot: Scenes with 3D nodes do not start on Android with Adreno 3xx and 5xx GPUs

[nimenko]

Bugsquad edit:

Adreno GPU drivers have broken OpenGL ES 3.0 support, and there's not much we can do about it without crippling Godot's renderer for correct driver implementations from other GPU vendors.

The fix will come in Godot 3.1 with the new OpenGL ES 2.0 renderer, which should run fine on Adreno GPUs and will be enforced when such GPUs are detected (at least until we get test reports that Adreno eventually fixed their bogus drivers for OpenGL ES 3.0).

In the meantime, a potential workaround is documented in https://github.com/godotengine/godot/issues/12816#issuecomment-355991771

---

Operating system or device, Godot version, GPU Model and driver (if graphics related):
Google Nexus 5 (Android 6.0.1), Godot Engine v3.0.alpha.build2, Qualcomm Adreno 330 (OpenGL ES 3.0).

Additional info:
Godot Engine build and export templates were downloaded from here.

Issue description:

If scene contains some 3D-related nodes (e.g. MeshInstance with primitive mesh), then application freezes at Godot Engine splash screen.

Logcat with opengl calls:
https://pastebin.com/S6Up0w7H

Maybe a driver problem?

[reduz]

probably something incompatible with Adreno 3xx, will need one to test.

[torugok]

Probably, a friend tested on an LG G2, with adreno 3xx, same problem,
I have no idea how to come up with a fix :/

[torugok]

The screen just freezes, no warnings, no logs, no infos, etc

[Alexia-AT-Digitecnology]

I have a Xiaomi Redmi 3s Pro with Adreno 505 and have the same error.

[endragor]

Encountered similar behaviour on some Adreno devices - the reason was that linking scene.glsl shader (glLinkProgram call) took enormous amount of time.

After removing shader parts related to USE_FORWARD_LIGHTING and fogs, linking started to take tens of seconds instead of infinity.

Not entirely sure this is the same issue though.

[PauloPatez]

Same here with Adreno 305. Some friends who own devices with Adreno gpus reported the same.
My project is pretty big and we're in middle stages of development, I'm very worried about this.

[PauloPatez]

@endragor can you provide steps (or a branch)? I'm not familiar with Godot renderer backstages.

[endragor]

See https://github.com/endragor/godot/commit/02b12c98043afa6418e0463204e638d6f435ed0a. I haven't checked recently if those removals help though, it could be that something new was added that also causes hanging.

[Alexia-AT-Digitecnology]

@endragor, does this removal of the shader solves the android crash problem?

[endragor]

@Alexia-AT-Digitecnology It solves freezing at the beginning which is mentioned in the OP. I didn't see mentions of crashes here, so I'm not sure which problem you are referring to.

[Alexia-AT-Digitecnology]

@endragor , when you run a Godot 3d project into a cellphone with adreno chipset, it crashes. It happens to me and a lot of friends. And mali chipsets too.

[endragor]

@Alexia-AT-Digitecnology then it is likely a different issue - please create a new issue on GitHub and attach a sample project to it.

[Alexia-AT-Digitecnology]

@endragor, it's issue #11693

[Alexia-AT-Digitecnology]

There is another issue related: #12192

[endragor]

So this is a duplicate of #11693, which also says there is a freeze. #12192 was a configuration issue. So do you experience a crash or a freeze? If it's a crash, then it is something different from the opened issues.

[PauloPatez]

Thank you, @endragor.
I reproduced this endragor/godot@02b12c9 and now it doesn't stuck on loading screen anymore, but 3D shaders are all black and performance is painful; 30fps with just one Sprite3D (20 with shaded flag on).
EDIT:
I had only built the export template after the scene.glsl modifications, I compiled the editor and everything is black there too; so it's a good thing, i guess. That means the hanging is the only issue here.

[vnen]

UWP also hangs if you add any mesh, I wonder if it's related. ANGLE seems to get into an infinite loop.

[akien-mga]

For the reference, we decided not to merge #14902 as it's too hacky and likely does not fix all Adreno 3xx issues. If you really need something that starts though, you can apply https://github.com/godotengine/godot/pull/14902.patch on your own branch to build Android templates.

As to a proper fix for this issue, it will boil down to waiting for a GLES2 renderer and somehow enforce GLES2 mode on Adreno 3xx.

[alex9099]

Not sure if i got that GPU but my phone also freezes in godot screen and crashes (xiaomi mi a1)

[set-killer]

@alex9099 Xiaomi mi a1 uses Adreno 506.
By the words from the developers, Godot should be running fine with this GPU.

[alex9099]

@set-killer on my phone it just crashes, maybe android version? i am using the latest version that i compiled, i am not sure if the export template that is downloaded automaticly works or if i need to compile myself

[akien-mga]

If you compile the editor yourself, you also need to compile the export templates you want to use.

[akien-mga]

There were several reports of non-working or crashing 3D with Adreno 5xx GPUs too, so edited the issue title to match those.

[ret80]

I wanted to clarify what is the plan to correct this problem?
Since the problem is very serious! Processors Qualcomm installed in half of the devices for android. In essence, this problem makes the android platform not suitable for distributing games on the Godot engine. Earlier decisions of this problem seem to me not correct.
1 Wait for the release of version 3.1 for an extremely long time (probably about a year).
2 To solve the problem by replacing OpenGLES 3.0 with OpenGLES 2.0 for processors with a Qualcomm is a very strange way.
What do I suggest:
1 In all likelihood, several GPU developers will have to be supported.
2 Perhaps it is worth discussing this with the developers of Qualcomm. Maybe they will propose something.
Please kindly discuss the situation.

[volzhs]

based on this announcement. https://godotengine.org/article/gles2-and-gdnative-progress-report-2

PLANNED FEBRUARY 2018

• meet with other developers at FOSDEM and GodotCon
• implement more shader features
• NativeScript 1.1 extension
• Rust binding guidance
• load meshes
• render meshes
• implement basic PBR
• directional lights

gles 2 renderer seems to be done in Feb.
maybe it might be delayed a little bit but I guess it will be done at least in Mar.
The official release date for 3.1 will be much later, but you can get gles 2 renderer before that.

[endragor]

1. GLES 3 is simply less perfomant and less supported on all mobile vendors than GLES 2, so GLES 2 as a default on mobile platforms does make sense. There is also still a significant market of devices that do not support GLES 3 at all.

2. 3.1 will be out sooner than a year from now, hopefully.

3. We develop a mobile game and with patches #14902 #15774 Godot works fine on Adreno GPUs. But without them, yeah, either don't develop a mobile game with Godot 3.0 or be ready to apply your own workarounds in the engine code.

[endragor]

Well, I should correct myself: you can develop your mobile game with Godot 3.0, as almost certainly GLES2 support will be implemented sooner than you finish your game.

Why was it necessary to do GLES3 and spend a lot of time if all the same all are offered to use GLES2? We have a bug but we say: we will not fix this bug. and so come down! use another engine or wait for GLES2.
I do not know what to say to this :(

@volzhs

implement more shader features
implement basic PBR
directional lights

And this all will work for GLES2 or not? If not, then why should we spend it all the time? If it works then is the sense from all these new things?

I wanted to clarify where did you get the statistics that GLES3 is not so common that it would be time to eliminate problems with it? According to Wikipedia, many GPU manufacturers have long supported the GLES3. You can easily verify this:
https://en.wikipedia.org/wiki/Mali_(GPU)
https://en.wikipedia.org/wiki/Adreno
https://en.wikipedia.org/wiki/PowerVR

And yet, here we are, with such a bad OpenGL ES 3.0 support that the engine crashes only on Adreno.

[ret80]

@akien-mga
63.6% of devices support GLES3. More than a half. Especially it is worth to finish the business started and not stop at the finish. Yes, Qualcomm has reworked this task, but other engines are coping with this problem. I'm sure that the Godot will do it.

[endragor]

Those problems in Godot come specifically from bad implementations of GLES3 by GPUs that are still in use. You can also search for benchmarks of other engines that can target both GLES2 and GLES3 (UE4, Unity) - same scene on the same device has significantly worse performance when rendered with GLES3. Or you can build your own benchmark, if you are doubtful.

I'm not sure how you draw conclusions from Wikipedia articles - there are no stats as to how many devices are actually in use. Unity had hardware stats page that could be used to determine which hardware mobile gamers actually use right now. It's down now for some reason, but the archived version can be accessed here: https://web.archive.org/web/20170729230854/http://hwstats.unity3d.com:80/mobile/gpu.html. So according to it about 35% of devices support GLES3. Even if it was 63.6%, as you claim, releasing a GLES3 game would mean discarding 36.4% of the market, which does fall into my measure of _significant_.

[ret80]

@endragor
From Wikipedia, I received statistics according to the year of release of the GPU and the version of GLS that it supports. The last GPU supporting only GLES2 ends around 2010. Even from the statistics that you instilled (sort the operating system android and see the last paragraph), it is clear that the largest segment with GLES2 is:

ARM ES2.0 Utgard: 26.5%

All the other items where GLE2 is mentioned occupy a small percentage. And if you put them all together, you will end up with about 36.4% of the market with GLES2. What does the link from @akien-mga:
https://developer.android.com/about/dashboards/index.html#OpenGL

I honestly do not understand why, after the team has done such a huge piece of work to support GLES3, suddenly you all start saying that GLES3 is not a thoroughfare for drawing graphics and in the foreseeable future it will be supplemented with a targeted GLES2 renderer!
At me (and not only at me) at once there are questions:
1 Why Godot 3.0 came out with the support of GLES3 and only GLES3 if a year ago it was clear that GLES3 is not promising at the moment?
2 Why, with the support of GLES3 and leaving Godot so much with GLES3, improving the support of facilities becomes not a priority?
Someone, please answer me these 2 questions!

PS
Problems with GLES3 are also on the Radion cards, and they are also not someone who does not want to notice. Everyone pretends as if they are not.

[endragor]

Yeah perhaps those stats are more accurate and there are 36.4% devices not supporting GLES 3, but, as I said, that's still significant in my opinion. Plus those who claim they support GLES3 may support it partially or with many bugs in driver implementation.

GLES3 was implemented mainly as a target for higher end devices and with advanced features in mind. There are things that you can't do with GLES2 or can only do them with significant sacrifices, while they can be implemented easily in GLES3. Some of those were listed by @reduz here: https://github.com/godotengine/godot/issues/14869#issuecomment-353516796 .

Now, I myself am still not convinced whether GLES3 is really a viable platform for complex games as there is evidence that its performance is poor in some cases, and I'm yet to see a game/demo with a complex scene and decent performance.

I can't answer the question (1) as it was @reduz's decision. Even if the answer is "it was fun for him to explore modern rendering techniques that cannot be implemented with GLES2", that works for me. It's work he was doing for free at the time, and as a result we are getting a FREE engine with astonishing capabilities and ease of use. And you just have to wait for a couple of months to get a working GLES2 renderer.

The answer to (2) is that it's not a priority to improve GLES3 on mobile as GLES2 will be the standard on that platform, so there is no point in adding mobile-specific hacks that will affect other platforms. For other platforms fixing GLES3 renderer is a priority, as far as I can tell. If you are aware of Radeon-specific issues, do report them, and there are some in the backlog scheduled for 3.1.

So be it. However, based on experience, I can say that a couple of months will not be enough to release Godot 3.1. When I designed Godot 3.0, I gave the most pescemal predictions from all on the forum. And they did not come true, it took more time than I expected. There is a suspicion that the same thing will happen this time. And that would make a correction to the already existing GLES3 will require less effort. And in a month you can release Godot 3.0.1
At the moment there was not a very good situation. The quality of stable version 3.0 leaves much to be desired. And if Godot wants to compete with Unity and Unrial, then the quality of the product will have to be kept at a decent level. And the development of new features is certainly great, but fixing bugs should be in the first place.

PS.
The lack of shadow on Radeon R7. No buffers are created in class "RestorizerSceneGLES3:initialize" line 4882. I raised this topic on Facebook. But there everything was dead.

sure, there are part phone only support gles2, not gles3. but they are old, the ram entirely small. other word, the one who uses the old phone, will not play 3D game. even can't use social app. like wechat, qq. not all the market is the qualified market. maybe it's better to do some trick to make godot-gles3 work well on adreno hardware. better including new feather ,sth like the one--tessellation.

[ret80]

@aron3097 You say it right, but everybody doesn't care. :)

Just for the logs, i have the same issue on Adreno 304 on a Lenovo TV-X103F (10" Lenovo Essential tablet with Qualcomm 1.3 quadcore) https://hastebin.com/calevamoqa.vbs

Is it possible to use a small whitelist for GPU's to fall back to GLES2?
Would be a good workaround for now.

FWIW Issue isn't reproducible on Google Nexus 5X on the same Android Build (with the same project & export settings) which has an Adreno 418

[clarkejm]

Was reading some other troubleshooting references related to this and I noted that in many of the cases the Device Manufacturer's ended up fixing this through Webview updates before Android 7. Since Webview is tied to Chrome version now, I thought I'd try updating the Pixel 2 to Android P beta and the issue is gone.

[reduz]

Kicking to 3.2, where it will probably be closed due GLES3 renderer being removed.

[endragor]

The bug reads more like "Godot doesn't support some Adreno GPUs", not "GLES3 backend doesn't support <...>". This should be fixed in 3.1 with GLES2 backend, so I think it needs to be tested and closed - otherwise people will think Godot still doesn't support mobile.

[akien-mga]

This issue should now be fixed when using the GLES2 renderer in 3.1 (currently beta 2).
Can anyone confirm that they can run 3D projects on devices with Adreno 3xx/5xx GPUs when configured to use GLES2?

For GLES3, this sadly can't/won't be fixed.

[ret80]

Confirm. The lighting doesn't work but at least it doesn't crash.

[akien-mga]

Thanks, closing as "fixed" (as best as we can, i.e. by providing a different renderer).

Specific bugs with the GLES2 renderer on such hardware should be reported in new issues, if not done already.
