Hello. During using Chromium on wayland I faced with an issue - huge white/black squads flickering over the screen, in case if I opened video into full-screen mode.

OS: Manjaro Linux den-pc 5.2.11-1-MANJARO Xorg-server 1.20.5-2 (Xwayland and all related packs the same version) Chromium (chromium) 76.0.3809.132-1 (tested and on downgraded version) Mesa versions - git-master, 19.1.5 (system) etc...

Steps:

1. Login into wayland session
2. Launch chromium
3. Open chromium into full-screen mode (it is important, because in other way bug can't be reproduced)
4. Launch any youtube video
5. Open video in a full-screen mode Result: picture starts flickering with white-black squads. Video attached.

I searched for same/similar issues and could find only these, quite old and resolved mostly: https://bugs.freedesktop.org/show_bug.cgi?id=106841 https://bugs.chromium.org/p/chromium/issues/detail?id=849682 https://bugs.freedesktop.org/show_bug.cgi?id=111140

Second thing - is that running with "--disable-gpu-driver-bug-workarounds" - resolves issue.

Bisection lead me to:

egl/x11: Support DRI3 v1.1

Issue doesn't exist on Xorg session. Possibly (as in found tickets) it may be related to regression in Xwayland, but I am not sure in this.
