[Bug 969860] Re: fglrx uses 100% CPU when screen turns off (spinning in glXWaitVideoSyncSGI or glXSwapBuffers)

 

Either the upstream bug was re-introduced or never really fixed because
I'm running the amd-catalyst-13.8 beta2 version (fglrx 13.2000).  As
soon as the screen shuts off, the CPU usages spikes to 100%.  Neither of
the workarounds work for me.  I've been forced to just turn off X at
night.

I've noticed the problem as well if I run xbmc as a standalone.  As soon
as the screen is shut off, the xbmc.bin process jumps to 100% cpu.  The
same is true when trying with fvwm2 or xfce4 as well.

can we get upstream to re-open the bug?
