I run kubuntu on an small htpc. The PC is connected to my TV via HDMI. Everything is fine until there is some movement. One half of the screen is a little off. Like this: example
The horizontal line, where the latency appears, moves after reboot, but is otherwise stable. I changed the cable, tried a difrent TV without any different result. This happens when I see a video or when the screensaver is playing.
I tried to change the videocodec, but maybe i didn't do it right.
I think, I need mostly some help, to describe my problem, so I can search for a solution.
Please, please, please help me somehow.
Edit: I don't know why you ask me about the flash player. I have this problem, when the screensaver is running, when I play video files like avi and so on and when I play a video game.
