[Bug 811573] Re: emacs window does not always draw properly (compositing bug?)

 

I seem to be affected by a variation of this bug. In my case,

STEPS TO REPRODUCE:
1. Logged in to "Ubuntu," open a text file, edit
2. Watch as, from time to time, 
2a. what you just wrote is invisible
2b. the blinking cursor seem to be stuck somewhere you just moved it from
2c. characters you just deleted are still there

EXPECTED RESULTS:
Draw text in text buffer in real time (without forgetting to draw them)

KNOWN WORKAROUNDS:
Switch workspaces (e.g. if emacs is on workspace 1, switch to workspace 2, then back to workspace 1)

System info:
* Laptop: System76 Pangolin panp7 / CLEVO
* Ubuntu 11.04
* linux kernel 2.6.38-11-generic
* graphics card: ATI Technologies Inc M92 [Mobility Radeon HD 4500 Series] (module: radeon)
* Compiz 0.9.4.0
* unity 3.8.16
* GNU Emacs 23.2.1
