Using Firefox has always been a nice Experience until the day this nasty Redraw Bug occured.
Opening a larger Amount of Tabs/Sites caused a Bug that made Firefox (3.0.5 in my case) to redraw only Parts of the Site. A Ghosting Effect that was really getting on my nerves, because you had reboot completely to fix it partially. Scrolling or resizing the Firefox Window sometimes redrawed Pages correctly, but still when opening a new Tab everything was mashed-up again.
According to Bug 434602 this has been fixed with a nightly Build (download link in the Thread).
For now it seems to be fixed. Let’s keep Fingers crossed…
Update: running 3.07pre now. Sites like http://events.carsonified.com/fowa/2009/miami/speakers cause problems while scrolling like not updating background images properly or loading images on-rollover only. Sometimes Background-Images are disabled/gone completely after switching Tabs.
