I'm uncertain if this channel is still open, but It seems that the problem has returned. I'm not quite sure why, I think it might be that I didn't properly update to boot parameters when I was testing kernel 5.3.0 - 994 but either way, it seems that the new kernel isn't a solution. On Tue, Sep 3,

booting with the parameter intel_idle.max_cstate=4 seems to have solved the issue, thank you. Is this a permanent fix or will I eventually need to alter this with a future kernel update? Also I'm curious as to what intel_idle.max_cstate=4 actually does. On Thu, Aug 22, 2019 at 8:00 PM Daniel van

Thanks. The videos seem to show this is a problem with aligning the entire display image. So it's not traditional "tearing", but I totally agree that "tearing" and "flickering" is the best description. Please try logging in to "Ubuntu on Wayland" and tell us if that avoids the problem. Please
