GPU-related artifacts

Description

From Twitter: https://twitter.com/JohnMarkoff2/status/1111299290268196864

My Brave experience has become so horrible. A new tab takes 3-5 secs, typing in the url bar has a lag of multiple seconds. While typing, the window turns to garbage. I deleted ~/Library/Application Support/Brave* and reinstalled and it's the same.

Automatic graphics switching does not have an impact, but I do have more than one GPU card.

Chrome works on the same machine.

It's only a brave issue and for me it didn't start until the Dev release w/ ads. It's actually a 2012 with a GeForce GT 650 running OSX Yosemite. No issues on my other computers. Running Brave immediately turns the fan up to max and I get that weird graphic effect.

GPU logs from Chrome and Brave (note different versions).
Brave managed to pick Apple drivers, while Chrome uses Intel (?)

Similar issue here, in Google Sheets. Version 1.10.64 Chromium: 81.0.4044.138 (Official Build) beta (64-bit). It's fine again after a reboot.

@larseggert if you run into this again, you can try disabling hardware acceleration under brave://settings/system

It would also be great to know more about your setup - are you on a newer core i9 MacBook? we have seen some errors with those where HW acceleration needs to be disabled for now

I've looked in detail and we're matching Chromium on everything, minus using finch experiments (ex: fetching blacklisted drivers from server)

It’s a max’ed out 16” MacBook, running on discrete GPU, since I have a large external monitor attached.

I think this is actually a Chromium issue, when it happens in Brave it also happens in Chrome.

I'm also encountering this issue.

I'm encountering the issue on several different websites at the moment.

The most recent was Twitter:

Artifacts present at the top of the Mentions section.

I've reproduced on at least 3 different occasions in Google Sheets.

Will disable hardware acceleration and report back if I reproduce the issue.

[kachapman]

Disabling hardware acceleration solved the problem, but created a new problem where certain web pages that were using it are extremely slow.

[kachapman]

The issue still persists in Version 1.14.81

[jeroenim0]

1.16.67 still present, restart of the browser solves the issue though. No need to reboot..
