Attached is a small animated GIF which causes nearly triple the CPU load
whenever it's on a page (even loaded seperately) in Firefox 1.0.
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

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.

Win2k, PIII mobile w/ 256m & nVidia GeForce 2 mobile
All the reproducers seem to have nVidia graphics chips...

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.

Nope, the non-transparent version works fine. Think you're right, it's the same
bug w/ nVidia drivers & transparent drawing.
