Public bug reported:
I am using xfce desktop.
Issue:
When I want to log out, after clicking on the log-out button from the
start menu (that one which looks like the power button on a tv-remote),
nothing happens for several seconds before the window to confirm the
logout/lock screen/shutdown appears and the X process is eating up 100%
CPU during that time.
The same issue I have experienced when I took the screenshot: After
pressing the key combination to take a screenshot, I had to wait several
seconds before the screenshot has been presented. During the waiting
period, 100% CPU was used.
Even some other things seem to react somehow sluggishly while others are
working as expected.
But when logging out, it is always annoying to wait so long for the window to
choose to log out/lock the screen/shutdown.
Expected behaviour:
* The logout window is displayed immediately (as before).
* The Screenshot is displayed immediately after taking it.
