Created attachment 611162 [details] Screenshot of Chromium 81.0.4033.2, showing the render error bug. Hello- After compiling/installing/running Chromium 81.0.4033.2 (from the Gentoo repo, no longer in-tree), I noticed a bit of mipmap noise being drawn at the outer edge of the browser window (screenshot attached). After submitting a bug to upstream ( https://crbug.com/1046122 ), thomasanderson@chromium.org suggested a patch that would fix it. I applied it (to 81.0.4040.5, which unfortunately changed two things at once, and thus made it more difficult to deduce whether it was the patch itself that helped things), compiled (a newer version of) Chromium again, and noticed the issue had ceased. The original Gerrit patch (which was applied against chromium/src.git master at the time) is at https://chromium-review.googlesource.com/c/chromium/src/+/2033759 , and after fetching it, I cherry-picked it atop the Chromium 81.0.4040.5 sources, and did a 'git format-patch HEAD^..HEAD). The resultant patch (which can be applied in in any order, as it doesn't touch (to my knowledge) any files that other patches might fiddle with) is attached as well. I'll keep following up on the upstream bug, and hopefully will get around to quickpkg-ing the current Chromium build, trying to rebuild it without the patch, and seeing if the bug comes back. Sorry for the incomplete nature of this report (and I completely understand if you aren't excited about folding this patch into the main Gentoo tree), but I thought I'd share what (little) I had sussed out from my bug-watching escapades thus far.
Created attachment 611164 [details, diff] Tom Anderson's patch forcing a redraw after a (WM-initiated?) resize of a browser window by invalidating the layout of the frame view. This is Tom Anderson's patch, cherry-picked directly from the Gerrit repo in question ( https://chromium.googlesource.com/chromium/src ), and turned into a metadata-rich patch with 'git format-patch'. Not technically necessary, but I wanted to make sure the commentary (and credit to Tom) remained intact.

If not, I will add to next beta/dev channel release. BTW: There is a "DOWNLOAD" Link in Gerrit where you can get the patch with all metadata much easier :)
