308417 - Causes input/render lag in fullscreen games such as Day of Defeat

Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[pyrogx1133]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4

If I leave Firefox Beta 1 running in the background while playing Day of Defeat,
 every so often the rendering of the game slows down.  It appears my frame rate
drops, but when looking at the frame rate counter, it is stable.

Once I close Firefox, it goes away and everything is smooth.  This problem did
not occur in previous version of Firefox.

I also noticed that when I exit my game, it appears that Firefox was using 33%
CPU usage for some reason.  This is probably the cause of the rendering lag.

Reproducible: Always

Steps to Reproduce:
1. Open Firefox
2. Run Day of Defeat

Actual Results:  
Firefox is taking some CPU time while idle and causing rendering lag in Day of
Defeat

Expected Results:  
Take little to none CPU time

do you still see this problem when using firefox version 3.5 or 3.6?
If not, please close the bug (resolution WORKSFORME is one possibility).
And if you do see the problem, please provide an update comment.
