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

 

Just a small heads-up:

Activating "Force full screen redraw (buffer swap) on repaint" caused a
significant increase in CPU load with regular usage on my system. That's
why I had to go back to deactivating the automatic screen switch
entirely.

In the course of doing so I discovered another bug in that the automatic
screen lock does not work as long as the display isn't turned off. Has
anyone else experienced something similar here?
