Corrupted shell

On boot gdm3 looks fine (displays a list of users).
When i choose a user from the list, the animation plays out - and that's when
the corruption starts (missing text and missing graphics).
I can still log in by typing the password.
Once logged in, gnome shell looks fine at first. Opening the Activities screen
might cause minor corruption (for example, hovering over icons on the left
panel might show corrupted selection rectangle fadein). Typing in the
Activities screen _always_ causes major corruption in visuals.
Only Gnome shell (top bar, Activities, window switcher) is affected.
Applications continue to be drawn correctly.

Gnome shell reset (Alt+F2, r) cleans up corruption from the shell (completely
or almost completely), but it quickly returns.

Tried changing radeon.gartsize on boot - no difference.

No errors on Xorg.log
No errors in dmesg

This is a regression (things used to work ~half a year ago)

  (also tried older kernels, as far as 3.8rc4 - same thing, this doesn't seem
to be kernel-dependent)
