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):
Steps to Reproduce:
1. Run battery charge monitor applet
2. Scroll browser window or play video with mplayer, etc
Actual Results: Scrolling stops for 1/10 second at 1/2-1 second
Expected Results: Smooth scrolling.
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
