Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

Since upgrading to Ubuntu 12.10 I'm suffering severe rendering issues in unity:

  • Some parts of any application (for instance Firefox, or emacs, etc) are blank, or are not rendered, or are blinking.
  • Some fonts in an application are not correct rendered, maybe only some part (see Eclipse screenshot).
  • There is some shadows in desktop background.

It's something that occurs from time to time (it's works great for hours and suddenly start to give this rendering problems).

I was trying to find a bug in launchpad but without success.

My card (using i915 module):

00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0042] (rev 02)

I've tried to reset compiz/unity or gnome but does not help.

Any tip?

Update: A Firefox screenshot of how my profile in Ask Ubuntu looks like now
