Reproducible: Always Steps to Reproduce: 1.Examine CPU usage 2.Open attached file "optn=1.gif" in Firefox 3.Repeat step 1 Actual Results: CPU usage rises dramatically when the file is displayed Expected Results: Nothing unusual Sorry, but I am unable to d/l a current build to check if this has been fixed. I thought you might find the .gif file useful.

I can't confirm this, the attachement sits on 0% CPU usage for me Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041108 Firefox/1.0
Same here. 0-1% CPU usage. Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 Reporter, post some info about your graphics card and drivers. Also, you might try updating them.
Matic, are you actually seeing the bug? This worksforme too -- 0% CPU with a current Linux trunk build.

Greg, I've modified the animated image. I removed the transparency from both frames. Is your CPU still pegging? It is probably a dup of bug 260676. This animate image also has 256 colors.

Think you're right, it's the same bug w/ nVidia drivers & transparent drawing.
