[gm45] garbled fonts

[David Monniaux]

Binary package hint: xorg

Sometimes, display fonts become garbled (see attached image). This affects all applications, including those not yet launched, until X is restarted.

The problem seems to occur particularly when using Firefox, but I was not able to identify a sequence of actions leading to it.

Status changed to 'Confirmed' because the bug affects multiple users.

[WheelDweller (wheeldweller-deactivatedaccount)]

I have several, Ubuntu Precise (12.04) on built-in Intel machines with this same corruption. It also effects the wallpaper over time, somehow. It's pretty debilitating across an entire day...

Thanks guys!

Broken glyph cache. Which is not the same bug as #3, WheelDweller you have a swizzling bug.
