Hi, On my system I have done this test and the trouble does not happen with Wayland, see my report and last comment in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=955585 I think those two bugs are the same (#954902 and #955585).
See also reports here: https://github.com/intel/libva/issues/357 https://github.com/intel/libva/issues/396 But is this an issue in libva? in mesa/libdrm?
