Compiz crashes on high cpu load

[christopherdstamper]

Binary package hint: compiz

Compiz works great. I didn't have to do any hacking or configuration to get it to work.

However, when the system is under high load (99% cpu) and I switch workspaces (ctrl+alt+bkspc), compiz almost always crashes. Iit starts the fallback wm (metacity). Alt+F2+compiz--replace puts me back in buisness, but it's a very disrupting problem...

Using ATI Radeon 9100, on an older P4 laptop, Ubuntu 8.10

 01:05.0 VGA compatible controller: ATI Technologies Inc RS300M AGP [Radeon Mobility 9100IGP]

I have this problem too. Nothing in /var/crash, just this in dmesg:
 [316398.163507] compiz.real[16854]: segfault at 0 ip (null) sp bfdbb7cc error 4 in libxml2.so.2.7.5[110000+122000]

Hope you mean ctrl+alt+arrow keys.

Otherwise I can reproduce it by starting a bunch of torrents and switching back and forth between workspaces until it crashes.

I tried installing all related -dbg packages but it didn't produce anything that looked useful, basicaly just removing "no debugging symbols found" from the above gdb trace.

Any suggestions on what else I can do to debug this?

Yeah i did, not sure what happened there... ;-)

But IIRC, upgrading to 9.04 fixed this issue for me.
