I upgraded my laptop to KDE-4.6 last night, which pulled in sys-power/upower-0.9.8 for the first time, and everything seemed to work fine (though I only looked at it for a short time before going to sleep). Today, I went into work and booted it on my docking station, but shortly after logging in, one of my two screens began intermittently going black. After Googling about a bit, I found similar reports for other distros (for example, Arch [1] and Ubuntu [2]). I saw reports for both ATI & nVidia cards, single and dual-monitor configurations. I was eventually led to a bug report for upower [3] indicating that this is a polling problem with docks in upower-0.9.8. The bug report indicates that a workaround is implemented in upower-0.9.9. I package.keyworded that, which successfully resolved the problem. I'm not aware of a useful log to provide, but if there is one, please let me know, and I can try to reproduce it if necessary.

I had the same problems for awhile while using kde 4.6.2. The flickering was present even if using kdm to log into another desktop environment (fluxbox) and launching any kde application, but did not seem to appear on the kdm login screen. After updating to 4.6.3-r1 + xorg-server-1.10.1.901 and using upower-0.9.9 + nvidia-drivers-270.41.06 the flickering stopped. Possibly unrelated but appeared at the same time, if I resize konsole (and only konsole) by dragging the corner, I get grainy screen artifacts and my kde locks up, requiring me to kill my X session. The grainy artifacts persist even if I kill X and restart the xdm service, and are present both on the kdm screen and desktop (and any run applications). Resizing konsole is still a problem for me in 4.6.3.
I should have noted in my comment that I was not able to find anything in any log file regarding the flickering, or any addition to the logs that coreletated with the time of the flickers. I watched dmesg, messages (I routed all normal logs there), x session errors, etc.
Before this turns into some discussion forum, CCing archteams for 0.9.9 stabilization...
