See attached screenshot. My X11 change from default for the "Tearfree" option is: Section "Device" Identifier "Intel Graphics" Driver "intel" Option "TearFree" "true" EndSection as /etc/X11/xorg.conf.d/20-intel.conf Copying the wallpaper to My Pictures and setting as wallpaper doesn't show the corruption. Using other wallpapers including included wallpapers shows no corruption. Removing the "tearfree" option then logoff/logon doesn't show the wallpaper corruption (but gives me screen tearing when playing videos, which I don't like. Using the Wayland option shows no wallpaper corruption.
