Unfortunately I have since got rid of that hardware. However even with
my new hardware (Nvidia NVS290), the issue is trivial to reproduce; with
and without compiz. Compile the below C program and watch the CPU usage
of Xorg. It's totally unacceptable to anyone with programming and
graphics knowledge...
#include <stdio.h>
#define LINES_PER_SEC 100
int
main(int argc, char *argv[])
{
int n;
for (n=0; n < 10000; n++)
{
usleep(1000000/LINES_PER_SEC);
printf("Hello world %d\n", n);
}
return 0;
}
