Apparently, this is not solved due to switching to UXA, but because UXA also reverts to DRI2.
SNA does work without issues, as long as it's combined with DRI2 and the xserver-xorg-video-intel driver. So this configuration works as well, and is probably preferable: /etc/X11/xorg.conf.d/20-intel.conf: Section "Device" Identifier "Intel Graphics" Driver "intel" Option "DRI" "2" EndSection However, removing the xserver-xorg-video-intel package and using the X modesetting driver will trigger this bug again, even when you force DRI2 with LIBGL_DISABLE_DRI3=1. The same goes for Wayland. -- With kind regards, Kevin Keijzer GNU/Linux systems administrator, LibrePractice https://www.librepractice.org/
