673608 - When force-enabling with i915, firefox is slow to the point it's unusable

Status: RESOLVED DUPLICATE of bug 670645

(Core :: Graphics, defect)

Description

I'm pretty sure this has to do with my graphics driver having bad support for my hardware, but just in case.

The problem happens when playing canvas rider. With layers.force-accelerated to off, the game is smooth and firefox takes ~100MB. When flipping the pref to true, the game is slow to death and firefox takes ~300MB of memory.

This sounds like bug 670645. This should be fixed with firefox 8.

Jonathan, can you try a Firefox beta build - http://firefox.com/channel - to see if your problem is resolved? If not, feel free to reopen this bug.
