tiling corruption video
Reproduced with:
- firefox and firefox-esr
- thunderbird
- konsole
- emacs
When running Gnome on XWayland, tiling corruption can be seen by rapidly
switching the windowing position from "maximize" to "view split on left" and
"view split on right"
With default Gnome shortcuts, launch Firefox, and rapidly press super-up /
super-left / super-down / super-right. As the window moves around the screen,
you should soon see mis-rendered tiled pixels all over the screen.
My setup is Debian testing on SKL GT2:
xwayland/testing,now 2:1.20.0-3
lib*-mesa/testing,now 18.1.4-1
I also tested with mesa master
ba1ebf2ee12 python: Specify the template output encoding
No corruption is seen when running with X instead of XWayland.</pre>
