The problem does not occur on the primary screen. Reproducible: Always Steps to Reproduce: 1. Start Firefox 4.0.1 2. Move FF window to secondary screen (right-of built-in Thinkpad LCD in my case) 3. Click on any menu in the menu bar 4. See the opened menu clearly Actual Results: 4. The menu opens but flickers when the mouse moves and is often completely invisible The bug disappears when I disable hardware acceleration
I already installed the newest Ati drivers, to no avail. Win7 version is 6.1.7600
