on bug 112266
from Jan Kowalski
I had this bug on tested kernels: 5.3.8, 5.3.9, 5.4.0-rc6, 5.4.0-rc7. I can confirm hangs occurred, when the cursor was moved after some time of inactivity (10-60 sec, depending on kernel version. 5.4.0-rc6 was the worst) in Firefox when watching fullscreen video (excluding 5.4.0-rc7), or in games. This bug was accompanied by another one - sluggish cursor, in 5.3 line with screen flickering at the cursor position, in 5.4 line barely visible, occurring every few seconds but without screen flickering, and feels inaccurate. I added this patch https://bugs.freedesktop.org/attachment.cgi?id=145971 on top of 5.4.0-rc7 and hangs are gone (thanks), but laggy cursor is still there.
