Googling centos 7 VGA...Controller
tells me that apparently 82Q33 refers to the chipset:
release date 2007.06 .

Don't know whether this helps:

The i915 driver is fairly rock solid - virtually all desktop machines
these days have on-board Intel video, it's the lowest common
denominator. And your chipset is not exactly cutting edge stuff.

Are there any errors in the logs - either kernel logs or X logs?

For some reason you say you disliked Gnome - but does Gnome show issues
(they use the same video driver)?

A long shot is the theme. Are you using some non-standard theme on your
desktop?

Finally, do you have a spare graphics card you could try in the
machine? (This is just to make sure there's no hardware problem.)
