Description of problem: Since I started using compiz and desktop effects, scrolling in firefox has become very slow. After turning the mousewheel it takes around 3 seconds for the scroll to actually finish. Very annoying. But downloading and starting Seti@BOINC made firefox completely unsuable. Even though the 2 setiathome processes are niced to 19 and shouldn't take any resources, firefox almost stops responding. It takes around 10 seconds between any input like scrolling the mousewheel och clicking on a new tab, or refresh of the screen to actually happen. I had to shut BOINC down just to be able to enter this bug. Something seems to be getting starved cause by watching activity with gkrellm you can see that it doesn't even try to scroll for 10 seconds, and then a short spike of non-niced execution when firefox actually does something. Version-Release number of selected component (if applicable): firefox-1.5.0.10-5.fc6 compiz-0.3.6-2.fc6 xorg-x11-server-Xorg-1.1.1-47.8.fc6 xorg-x11-drv-ati-6.6.3-1.fc6 Linux razor 2.6.19-1.2911.6.5.fc6xen #1 SMP Sun Mar 4 16:59:41 EST 2007 i686 athlon i386 GNU/Linux How reproducible: 100% Steps to Reproduce: 1. Start firefox 2. Start BOINC and run Setiathome 3. Try to use firefox when BOINC is running Actual results: Firefox unusable, with 10 seconds passing between inputs and results Expected results: No starvation since it's niced processes in the background Additional info: The copmuter is a DUAL AtlonMP machine. Graphics Card: Ati Radeon 9200 SE Running under xen with the last working kernel (bug: 234008) Firefox has been slow since i started using desktop effects, but this seems to exaggerate the effect. It's probably not firefox's fault, but I don't know how to pinpoint which part is actually causing the slowdown, but now I have a way of really showing that something is causing firefox sluggishness. Is there any kernel parameter I can tune to try to work around this for now?
Does this happen to any other apps? Possibly X...
No not really. You can see it a tiny bit in evince too. I'm not sure about openoffice.org cause I'm afraid to use it cause it spins X into an infinite loop, but I should file a separate bug on that. However, I managed to get Firefox a bit usable again by tweaking options in xorg.conf: Section "Device" Identifier "Videocard0" Driver "radeon" Option "AccelMethod" "XAA" Option "AddARGBGLXVisuals" "true" Option "AGPFastWrite" "yes" Option "AGPMode" "8" Option "BackingStore" "true" Option "ColorTiling" "on" Option "DynamicClocks" "on" Option "EnableDepthMoves" "true" Option "EnablePageFlip" "true" Option "RenderAccel" "true" Option "UseFBDev" "true" Option "XAANoOffscreenPixmaps" EndSection With these options I can use firefox at the same time as Seti@BOINC. I suspect that it is an issue with Xorg's radeon driver or Mesa, but I don't know which one is responsible and firefox is the only app that's really hurting. Should I try to pinpoint the exact option that makes firefox go super slow?

Scrolling sucks, yes, we know.
