Re: Xorg 7.2 and 9746 freeze
I think it is because of composite extension. Using xorg without it for a couple of days and everything was ok.
Now I reenabled composite and first issues started to show up. After six hours of uptime, Xorg is using a large amount of memory (370MB and growing), and I'm afraid it will fill up all memory.
For now I'll disable composite again.
