|This is a very strange problem that I was hoping someone could help troubleshoot.
My KDE desktop "flashes" and often does not update. The problem occurs after about 10 minutes after rebooting, and only if I have multiple virtual desktops. (Switching from desktop to desktop seems to aggravate it.) By deleting all the config files in my home directory, I can solve the problem, but then have to re-setup my KDE sytem.
I'm using an nVideo graphics card with the nouveau driver in a monolithic kernel.
"Prepackaged" Linxu distros such as Mint work fine from a live CD, and I have swapped lots of hardware so I am confident that this is not a hardware problem.
The problem occurs in both AMD64 and testing (~AMD64) systems.
Here is a video to show the effect:
It appears to be very similar (if not identical) to this bug:
Other than not using virtual desktops, can anybody suggest any troubleshooting to isolate this?
