Bug 804158

I'm experiencing Very poor graphics performance with F17. The problem has come and gone between updates since alpha 1. With a currently updated system I'm experiencing the following:

 * Playing a video in totem (or flash for that matter) takes up most of the CPU
   as reported by top.
 * I can see windows (like xchat-gnome) redrawing as they are resized or
   refreshed.

System is really unresponsive. I'm not using software rendering:

tbzatek reported seeing a similar problem, and it went away when running a custom kernel.

I feel bad for filing a bug report like this, with little concrete information. Please let me know what further information I can provide.

I'd love to work with someone on this to try and determine what the issue is before Fedora 17 is released, so that others don't run into a similar issue.

A fully updated Fedora 16 on the same hardware does not exhibit the problem.
