NEEK with Quartus 10.0 produces LCD jitter

Hello everyone, 

recently I moved a project from Quartus II 9.1 to 10.0. It worked out to be quite easy. However, my display now starts to jitter. It looks like the SGMDA cannot deliver data to the video_sync_generator in time resulting in slight shifts of the scan lines. I played around with timing constrains and changes to the SOPC design without success. It works fine in 9.1 but does not in 10.0. Anyone experienced the same problem?

sometimes it is only the software flaw!~
