Thanks for your hint!

Unfortunately I have never worked with a clock enable and I'm not sure if this causes the problem I got. Because I just use the 10Hz clock to move the graphic on the screen to the left/right/up/down and not for synchronization or something else on the screen. I also tried to use the pixelclock instead of the 10Hz clock. I had the same problem like before but also the problem that it was impossible to control the position of my square because it moved very fast to the corners of the screen.

Thanks for your help,
