From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5) Gecko/20031110 Firebird/0.7 Description of problem: I've been noticing non-smooth scrolling and video playback on my Dell 610 (ATI Radeon Mobility). I belive the cause is having the "battery charge monitor" applet running. It must be reading the charge information from a /proc file every second or so, because video or scrolling suddenly pauses for 1/10th second at roughly 1/2-1 second intervals. My guess is that reading this information triggers a global kernel lock and this stalls X updates noticably. Removing the applet from the panel restores smooth scrolling and video playback. I'm using acpi, but my recollection is that this also occurs with apm. Version-Release number of selected component (if applicable): 2.4.1-1 How reproducible: Always Steps to Reproduce: 1. Run battery charge monitor applet 2. Scroll browser window or play video with mplayer, etc 3. Actual Results: Scrolling stops for 1/10 second at 1/2-1 second intervals. Expected Results: Smooth scrolling. Additional info:
Have a look at bug #97322. Lowering the frequency of checks is appropriate, but I guess that's not enough to solve your video problem. Maybe the patch(es) of bug #104292 solve your problem?
Do you still see this problem with Fedora Core 2?
No response, assuming not
