Bug#837786: mutter: Issues repainting the display on mouse movement

[John M.]

I tried setting the "DRI" option to "false" (and to "2", as suggested
by ArchWiki), but the result is the same ---maybe due to the fact that
I also have a discrete display (Nvidia Optimus):

$ sudo lshw -c video

Or maybe it's something in my modprobe.d directory:
