Thanks Enrico,

I am not familiar with the modesetting driver. Nevertheless, after doing some reading,
I understand that it is a generic driver (maybe using a frame buffer?) and avoiding
specific intel acceleration primitives.

I modified
	/etc/X11/xorg.conf
and replaced
	Driver "intel"
with
	Driver "modesetting"
then logged out/in.

So far it looks mostly OK. Reinstalled evince and it does not crash.

MythTV seems to perform fine.

Watching youtube in a resolution of FHD or UHD (full screen) does show some artifacts.

I need to learn what settings modesetting accepts (if any) to tune its performance. I will keep it for the moment.
