Description tempel.julian 2019-09-25 14:05:49 UTC

TearFree works in general, scrolling in Firefox is free of tearing with it without compositor.
But as soon as I enter fullscreen mode, it is broken afterwards.

This is on Gemini Lake and
recent xorg-server-git master, xf86-video-intel-git master

Attaching dmesg.log and xorg.log.

I reported a similar issue for xf86-video-amdgpu which got fixed:

I suggest bisecting Xorg...

Probably the fallout from

    present/scmd: Check that the flip and screen pixmap pitches match

Thanks for your response.
This commit already has been reverted in master/1.20 branch, it is not at fault in this case.
