Comment 23 for bug 1072206

I am unconvinced by the workarounds suggested for this bug. I have recreated this in all situations: it is related to nvidia card memory size. Whatever workaround you try I suspect if you keep opening new windows you will get the bug eventually (I do). Its easier to recreate on a dual head machine or high resolution system. Swapping the nvidia card for one with a larger memory also means you can open more windows until the problem occurs. But it always occurs eventually. As I generally operate with 50 or more windows open, I don't have much trouble recreating this.

Also over time, the number of windows required to be open for the bug to appear reduces, which suggests a memory leak somewhere.
