--- Comment #12 from Artem S. Tashkinov t.artem@mailcity.com 2011-03-06 16:59:26 CST --- Probably it's a bug in X.org server itself or maybe this demo/wine makes an awful lot of "wrong" system calls.
I've attached strace to a running demo and it shows this:
# strace -c -p 21109 Process 21109 attached - interrupt to quit % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 100.00 0.000498 0 135798 sched_yield 0.00 0.000000 0 8 6 read 0.00 0.000000 0 2 write 0.00 0.000000 0 2 getpid 0.00 0.000000 0 2 ioctl 0.00 0.000000 0 3 gettimeofday 0.00 0.000000 0 2 poll 0.00 0.000000 0 4 rt_sigprocmask ------ ----------- ----------- --------- --------- ---------------- 100.00 0.000498 135821 6 total

However it's worth noting that even though I ran the demo with the least priority (20) I could hardly move any windows, Alt-Tab between them or do anything beyond watching the demo (mind that I have a quad core CPU and my system was otherwise completely idle).
