Public bug reported: Hello,
After the last update of saucy (with -proposed), I noticed that in some cases the display freezes while flickering. This flickering lasts a little moment, but is bothersome and is 100% reproducible. I've uncovered these two ways to reproduce this 1. On Firefox, start a flash video and wait for the screen to dim. 2. Install chromium-bsu (the game) and destroy an enemy ship. I did uninstall u-s-c in order to see if the bug was still reproducible and no, it disappeared after uninstalling u-s-c. My processor is an Intel Core Duo with 945GM.
