Brave-browser: Google Maps trackpad zoom is oversensitive

[stshank]

Description

Google Maps zoom is very twitchy with two-finger drag up and down on trackpad.

Steps to Reproduce

1. Open maps.google.com
2. Zoom in or out by swiping two fingers up or down

Actual result:

Map view jumps dramatically across several levels of zoom.

Expected result:

Map view gradually zooms in or out.

Reproduces how often:

Always

Brave version (brave://version info)

Brave | 1.17.48 Chromium: 86.0.4240.111 (Official Build) dev (x86_64)
-- | --
Revision | b8c36128a06ebad76af51591bfec980224db5522-refs/branch-heads/4240@{#1290}
OS | macOS Version 10.15.7 (Build 19H2)

Other Additional Information:

• Does the issue resolve itself when disabling Brave Shields?
  no

• Is the issue reproducible on the latest version of Chrome?
  no

Miscellaneous Information:

Using the + and - buttons on the website interface is a workaround, though it loses zoom animation steps that Chrome shows during the zoom level transition.

Running into the above as well. It becomes really painful to use Google Maps. Takes a lot of patience to actually get it zoomed to your desired view. I just started using Google Maps on mobile instead when I need to check something quickly.

Reproduced on macOS 10.15.7 x64 using the following build:

Brave | 1.18.10 Chromium: 86.0.4240.111 (Official Build) nightly (x86_64)

OS | macOS Version 10.15.7 (Build 19H2)

Also seems to be happening on Win 10 x64 when using the trackpad. However, when you use a mouse with a wheel, experience is pretty good.

[kjozwiak]

@rebron mind checking this on your Win 10 x64 laptop? Do you get the same experience/results when using the trackpad?

[rebron]

@kjozwiak Same fast zoom on Windows. I'm actually missing a "slow streets" layer as well which is showing up in Chrome. There is a slower, smoother scrolling.

cc: @pes10k @pilgrim-brave Any ideas on this one? maps.google.com has a smoother/slower zoom in/out behavior via trackpad on Windows or macOS in comparison to us where it's a much more faster/extreme zoom.

[darkdh]

If you take a closer look on zoom factor of url address, Brave increase/decrease the factor by 1, while other browsers can do it by granular fraction

[fabricapo]

+1 on this one. It makes me consider going back to Google Chrome, sadly. I am on MacOS Catalina 10.15.7 with a magic trackpad, Brave Version 1.16.68 Chromium: 86.0.4240.111 (Official Build) (x86_64)

Can y'all check whether GPU rendering is available on Google Maps? Switch to satellite view -> check the lower right hand corner for "3D Earth is not available" text. If the text is there, then you're using the tile based map rather than the vector/GPU based map which has far fewer features.

I think these complaints are all a symptom of a much more annoying problem, that Google Maps isn't serving the GPU accelerated version of the app to Brave. That feature enables fractional zoom, 3d buildings, and a lot of other QOL stuff.

[fabricapo]

Nope, I do not see the "3D Earth is not available" text when I switch to Satellite view.

"Google Maps isn't serving the GPU accelerated version of the app to Brave" means it will never happen, or do you think there will be a trick to activate it? If the probability is low, I'll move back to Chrome (sadly)

[stshank]

I do see the "3D Earth not available" text on Brave. However, IIRC Safari
doesn't advertise GPU availability and it zooms in and out smoothly. (I
could be out of date re. Safari.)

Hi @stshank @kaytwo and @fabricapo, i have a candidate for the issue here (looks like one of our WebGL related fingerprinting protections is getting applied w/o checking whether shields is at "default" or "max" protections). Im working testing a fix now and hope to have a solution (or at least crossed off a potential cause) shortly. Thanks all for your help!

[kaytwo]

Awesome! FYI I run www.google.com with shields down and am still seeing this issue. Feel free to ask for more info.

[pes10k]

@stshank @kaytwo and @fabricapo just a heads up that a fix for this is in nightly now, should be in the next nightly build, and will get uplifted to 1.17. Thanks again for the reports and help!

[kaytwo]

Thanks! Fix works for bringing back GPU accelerated (vector maps, fractional zoom) maps, but Brave seems to not be getting the 3d version of satellite maps, even in nightly with shields down. I can definitely open a new issue for this, I dunno how many other people are having this issue.

[pes10k]

@kaytwo how can i test for that? I can get a 3d version of google maps (nightly, macos build here, 1.18.43), though I dont know if its touching the GPU. Is there a place you're checking that explicitly says "3d accelerated" and it says no? Or are you just not getting any 3d version at all?

Also, i know we had some issues a while back with GPU's not getting trigged on some linux machines (iirc, some chromium-side GPU code was only being turned on by Google's field-trials code, so was off for all Brave users). I think we sorted that out, but if you're on linux that might be the issue. If thats the case, can you let me know what you see at brave://gpu/ and I can make sure the right people see it?

Thanks again! :)

(edit; probably just the "Graphics Feature Status" part of brave://gpu would be helpful tbh)

[kaytwo]

I figured it out. My Chrome install had logged me in to Google so it was picking up my "default to globe view" setting, but Brave Nightly didn't have that, and to get globe view you've got to click the little globe in the lower right hand corner. Everything works now, this is user error.

FWIW beta chrome://gpu and (beta & nightly) brave://gpu are bit for bit identical (however brave://gpu still sets the page title to chrome://gpu).

Thanks for following up!

[pes10k]

Phew! Thanks for letting me know @kaytwo , glad its sorted :)

My Google Maps is doing the weird zooming thing for the past few days, and I just checked and it says "3D Earth is not available". Shields are down for all google sites for me -- how do I fix this?

[kaytwo]

Are you on Beta or release channel? The fix for this issue is currently in nightly but not yet in Beta/Release.

[yamnitsky]

I believe I'm on the release channel, Version 1.16.75 Chromium: 86.0.4240.193 (Official Build) (x86_64)

[rebron]

Verified that zooming in and out is looking good for me, smoother scrolling as expected versus scrolling several levels on swipe up/down or pinch on:

[stshank]

Ah, yes, now working for me as well on Brave dev channel.

@mattmodarres do you have strict / max fingerprinting protections? If so, then this is not a bug; those are advertised as potentially breaking sites.

if you're seeing the issue in the default configuration, please let us know
