295.40 Drivers and Xorg 1:7.6+12 HIGH cpu usage

[norrland]

Hi, hopefully I'm not the only one with this problem.

Running Debian Wheezy with linux kernel 3.2.0.2-amd64 and the 295.40 drivers from debian non-free repository.
Using LXDE as DE and not that much fancy stuff.

But as of yesterday the Xorg process started hogging all cpu when I were switching between windows. So currently I'm using the nouveau drivers just to have a usable system.

Here are some info about my system.

Hope this will help. I've attached the nvidia-bug-report.log.gz

Was yesterday also the day you installed libcairo2 1.12.x? It seems to expose some wonderful new bugs in the drivers and performance really falls off a cliff. Going back to 1.10.2-7~bpo60+1 from backports seems to fix it for me.

Thanks!
Works like a charm
