Thanks all for the time spent investigating! All of this points to a freeze during rendering just like #41614 so I'm closing this issue as duplicate again.

The original description suggested it could be something else and the one call stack with __cxa_pure_virtual still seems weird to me but we'll see if that happens again once the nvidia driver issue is fixed.

Edit: Rolling back to nvidia drivers 450.57 might help, it fixed the issue in some similar cases.

I'm not able to reproduce the issue on Ubuntu 20.04 with either Gnome or dwm.

If you don't mind spending more time to check, there are a few other things that might help investigating:

  • Can you reproduce the issue on 3.2.4 beta?
    https://downloads.tuxfamily.org/godotengine/3.2.4/beta1
  • Can you reproduce the issue when starting Godot master with --single-window? You need to start your project directly using -e --path [path_to_your_project] for this option to work properly.
  • Would you be able to run Godot from vs code or another debugger? I'm interested in pausing Godot from the debugger while it's freezing to check the call stack on the main thread. Let me know in case you'd like to try that and need more details.

Duplicate of https://github.com/godotengine/godot/issues/41614.

Can you reproduce the issue on 3.2.5 beta?
https://downloads.tuxfamily.org/godotengine/3.2/beta5

I guess you meant to reference 3.2.4-beta1 and not 3.2-beta5? :)

Duplicate of #41614.

While it might also be caused by the Nvidia driver, there's a crash stacktrace here, I'm not sure it's exactly the same.

It looks like it could be a different issue, possibly due to #41910. This one is a complete softlock on the main thread after the popup appears, while the issue with the nvidia driver is a freeze for some time before the popup is rendered.

Yes, fixed! Thanks :)

I'm not able to reproduce the issue on Ubuntu 20.04 with either Gnome or dwm.

If you don't mind spending more time to check, there are a few other things that might help investigating:

* Can you reproduce the issue on 3.2.4 beta?
  https://downloads.tuxfamily.org/godotengine/3.2.4/beta1

Doesn't freeze on Godot Engine v3.2.4.beta1.official 

* Can you reproduce the issue when starting Godot master with `--single-window`? You need to start your project directly using `-e --path [path_to_your_project]` for this option to work properly.

Doesn't freeze with --single-window option.

It looks like it could be a different issue, possibly due to #41910. This one is a complete softlock on the main thread after the popup appears, while the issue with the nvidia driver is a freeze for some time before the popup is rendered.

Tried 8a84b3cfd352adac4c5a35d599be8d83db3ba8d9 which is before #41910 and Godot still becomes unresponsive. (Godot Engine v4.0.dev.custom_build.8a84b3cfd)

While it might also be caused by the Nvidia driver, there's a crash stacktrace here, I'm not sure it's exactly the same.

I killed with xkill. That's why there's crash stacktrace. In the stacktrace is mentioned that it was killed. 

* Would you be able to run Godot from vs code or another debugger? I'm interested in pausing Godot from the debugger while it's freezing to check the call stack on the main thread. Let me know in case you'd like to try that and need more details.

This would be interesting. Tell me all the tools I need to set up for it. I don't mind sharing my screen on for example Godot's Discord server.

@DavidHusicka Thanks for testing! Since it's not due to #41910 it's probably not the threading issue I was thinking about. And it's nice to know it doesn't affect the incoming 3.2 release.

For the debugger, you just need to install Visual Studio Code (there are probably alternatives but I haven't tried). This is how you set it up for Godot:
https://docs.godotengine.org/en/3.2/development/cpp/configuring_an_ide/visual_studio_code.html

There are a few differences though for master compared to 3.2:

  • platform=linux instead of platform=x11 in tasks.json
  • godot.linuxbsd.tools.64 instead of godot.x11.tools.64 in launch.json

Then when you experience the freeze, press pause in the run bar:

And on the left side panel, go to the run tag, open the callstack on the main thread, right click in the callstack and select "Copy Call Stack".

One last thing I'm interested in, is to get extra log about x server events. For that, open platform/linuxbsd/display_server_x11.cpp, uncomment line 87:
#define DISPLAY_SERVER_X11_DEBUG_LOGS_ENABLED

After compiling again, you will see more log in the console. I'd like to see what you get when the freezing occurs.

@pouleyKetchoupp
Hey i'm having the same exact problem as OP has, with the difference of the popup window showing but it dosen't seem to render(transparent with borders and contents behind it are inside the window like a image).
that the the whole application softlocks and i cant click or interact with anything in the application and i have to manually shut it down via htop.

@Michael-Sjogren Thanks! That helps a lot. I'm still not sure what happens, but the pure virtual call in the callstack indicates something might be called on a destroyed object. I'm trying to do some guess work but no luck so far.

Do you mind giving me the same information again, but this time with also the value of some variables in DisplayServerX11::process_events (if the debugger allows you to get them)?
window_id
wd.x11_window
wd.event_callback.object

pouleyKetchoupp picture pouleyKetchoupp on 23 Oct 2020

So i set a breakpoint on DisplayServerX11::process_events when im about to open a popup?

No, rather by pausing when it's frozen like you did before. It's a few levels up in the call stack you shared.

pouleyKetchoupp picture pouleyKetchoupp on 23 Oct 2020

Im watching them in my watch tab in vscode, but they have no value unfortunately perhaps i wrote the expression wrong?
watchvariables

Michael-Sjogren picture Michael-Sjogren on 24 Oct 2020

@Michael-Sjogren Make sure you click on the line that says DisplayServerX11::process_events in the call stack when Godot is paused (the other lines will be a bit different in yours):

Your variables seem ok. You will get something similar to this:

Then please add the terminal output from the same debugging session so I can cross-reference the numbers. Thanks!

Thanks! This call stack is different from the previous one, and actually points to possibly the same issue as #41614 (it's freezing while rendering, blocked on nvidia side). That means there could be two different issues here, I'm not sure.

If you can change your nvidia driver version, try installing version 450.57. It might help if it's actually due the nvidia driver bug.

Godot version:
4.0

OS/device including version:

Linux version 5.4.0-42-generic (buildd@lgw01-amd64-038) (gcc version 9.3.0 (Ubuntu 9.3.0-10ubuntu2))
Nvidia GeForce RGX 2080Ti
Vulkan 1.2
AMD Ryzen Threadripper 2950X 16-Core Processor
Using the nvidia 450 driver.

Having the same problem. Not completely sure what is going on yet, but at first glance it seems to be blocking in vkDeviceWaitIdle for ages.

@Darkheron Please surround large blocks of text with triple backticks like this:

```

This prevents them from taking too much space and also makes sure issue references aren't accidentally created. I edited your comment, but remember to do this next time :slightly_smiling_face:

I am sorry for being inactive lately. I will try to send my debugger output ASAP. Also, I am interested in finding the commit when this appears for the first time (which might help with some insight).

Thanks all for the time spent investigating! All of this points to a freeze during rendering just like #41614 so I'm closing this issue as duplicate again.

The original description suggested it could be something else and the one call stack with __cxa_pure_virtual still seems weird to me but we'll see if that happens again once the nvidia driver issue is fixed.

Edit: Rolling back to nvidia drivers 450.57 might help, it fixed the issue in some similar cases.
