Description of problem:
Slow response (1 to 3 sec lag) of KDE Plasma components, most notably Kickoff.

Version-Release number of selected component (if applicable):
1.7.1-7

How reproducible:
every time

Steps to Reproduce:
Launch an application from KDE kicker and wait.


Additional info:
This problem has been looked at in some detail here:

The problem can be isolated to the following patch:
xserver-1.7.1-window-pictures.patch

If I modify the patch as suggested in the above link, namely only apply the first section of the patch:
-    pPixmap = (*pScreen->CreatePixmap) (pScreen, width, height, pDraw->depth, 0);
+    pPixmap = fbCreatePixmap (pScreen, width, height, pDraw->depth, 0);

 , everything works fine, including the picture window problem this patch addresses.
