--- Comment #3 from Ilia Mirkin <[email protected]> --- (In reply to Allan Sandfeld from comment #2) > The original qtwebengine bug is at > https://bugreports.qt.io/browse/QTBUG-41242 > > One interesting thing I discovered was that using the EGL/GLES mode instead > of GLX/GL solved the issue. I assume at your level it shouldn't be that > different. So it could be a difference in how EGL vs GLX acts. The issue was happening for me with Unigine Heaven run with DRI3 + DRI_PRIME=1. Then I started running it with vblank_mode=0 and all my problems disappeared. I haven't checked whether removing vblank_mode=0 would cause the issues to reappear. I was happy to blame it on the DRI3 boogeyman and moved on (I tend not to have a good grasp on these types of issues in the first place... normally I wouldn't touch DRI3 but it really makes nouveau dev quite a bit easier with a primary non-nvidia adapter since I can load/unload nouveau/nvidia at will and still have things display on my regular screen). Not sure how vsync would cause the problems, but I was getting actual shader traps reported in dmesg. Do you (or whoever is having the issue) have that as well? -- You are receiving this mail because: You are the QA Contact for the bug. You are the assignee for the bug.
