Bug 91081 – Rendering animated GIFs in Firefox 1.0.3 causes Xorg CPU use to go crazy

• Product: Gentoo Linux
• Status: RESOLVED UPSTREAM

[Description Garrett Cooper 2005-05-01 13:24:14 UTC]

Whenever I go to the given webpage my X.org CPU use goes insane and whenever I leave the webpage the CPU usage settles down to near 0 for X. The issue is most likely the extreme number of animated GIFs in the background of the webpage.

Reproducible: Always
Steps to Reproduce:
1. Go to website.

Actual Results:  
CPU usage goes up quite a bit.

Expected Results:  
Used little CPU or at least less than it did.

Eats 50% CPU in FF 1.0.3 on Windows XP. If this is a bug, then it

Eats 50% CPU in FF 1.0.3 on Windows XP. If this is a bug, then it´s an upstream one. 

Anyway - any person who produces such "webpages" should be jailed immediately for life, any probation ruled out. *Disgusted*

[Comment 3 Garrett Cooper 2005-05-02 13:55:08 UTC]

Heh, well that's my opinion too but then again I don't say that to friends. Interestingly enough I don't think it affects my WinXP Firefox as much, but that may depend on your CPU speed compared to mine *shrugs*.

[Comment 4 Jakub Moc (RETIRED) 2005-12-22 20:50:16 UTC]

Well, I can't check any more with FF 1.5, the webpage looks way more sane now... :) 

Anyway, this is pretty much an upstream issue. Closing.
