In my testing I found this has various consequences depending on what program is being run;= I found it is pathological for watching a video fullscreen with mpv, in which case you are locked out of the desktop until the video ends with no way to recover; that was the most severe adverse consequence I have seen so far; of course my testing is not exhaustive. The bug also happens on suspend-resume, at least on my machine. I found aft= er a resume, restarting the X server by logging out and back in was enough to get hardware accel working again. Whereas following a manual VT switch, the only reliable way to get accel working was a full reboot. But maybe I just got l= ucky with the suspend-resume case. --=20 You are receiving this mail because: You are on the CC list for the bug.=
