I did some additional tests: - First by testing with the future kernel under development (5.4 RC0) and I found the same problem (no improvement)
- I searched the web and found similar problems with other people like for example here: https://bugzilla.redhat.com/show_bug.cgi?id=1723167 https://ubuntuforums.org/showthread.php?t=2339302 Following their recommendation, I therefore disabled the Intel PSR function in the grub configuration ("i915.enable_psr=0" in /etc/default/grub) so that the kernel does not activate it at boot time and indeed with this feature disabled, I no longer have the display corruption problem. The problem is that this feature is used to last longer on battery, so it's something useful on a laptop (especially since it worked well with older kernels <5.2). Could you please fix the display corruption problem without disabling this power saving feature for cpu intel. In the meantime, I leave this feature disabled because display corruption is too annoying.
