Applications redraw frantically (blink white) for a couple minutes and then it stops. I made a video showing the issue. It is very weird behaviour.
What is even strange (or a clue?) is that:
- if I have a system menu open (mouse right click menu) then there is no redraw whatsoever
- also if I have the unity dash opened then the windows redraw underneath it!
It stops after a couple minutes (when the notebook heats up?)
It happens always after boot and after resume from a longer suspend period.
Everything blinks except the unity side launcher, top status bar and unity dash.
I am running:
- 12.04 fully updated.
- standard base video driver. Tried the flgx but got stuck in 2D mode (the issue did not happen there). Logged in gnome and it didn't happen either.
- Dell Inspiron with hybrid video (Intel + Radeon HD 6400M)
Any ideas what it is or how to find a solution?
