After updating to 6.13.1, things like opening a right-click menu or a
file-dialog (which fade in) became extremely slow. I bisected this to commit

kms: add support for the MSC swap & sync API
This patch is mostly a port over of Intel ddx code for
MSC support. It needs a radeon KMS module with version
2.4 which has the query for hw crtc id.

So apparently this is related to the swap&sync stuff. My card is a Radeon X1900
XT. Versions of other relevant software on my system: KDE 4.5 rc1, kernel
2.6.35-rc2, Xorg-Server 1.8.1.902.
