Option "AccelMethod" "XAA"
This certainly helps for my after-suspend rendering problems. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It would be interesting wich EXA acceleration breaks it. Could you test the available "EXANo*" options to figure this out?

Therefore I'm closing this one now as fixed.

It may also work around the performance issues.

But I'm afraid there is a reason, why "greedy" is *not* the default. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
