Public bug reported:
After the upgrade to Ubuntu 12.04, many rendering glitches started to
appear in the UI:
- the shadows appear to be painted over and over without redrawing things under
it, so they eventually completely obscure the things below them; for example,
the top panel will obscure the firefox tabbar, and mosuing over Dash will cause
the shadows to become completely black
- there are transient 'gaps' in the launcher, ocyping roughly 1/3 of its
height, where it is not rendered at all; the borders of the gaps are flickering
and dynamic. a similar glitch happens in Dash
- the translucent background of the launcher is sometimes painted several
times, so it appears darker than normal
- the top panel sometimes flickers
These issues do not make the system completely unusable, but complicate
its use, especially the shadow problem.
