Can confirm that issue - on flash in browser, mplayer using vdpau, or vlc. Only for me the line is in the upper third of the video, and it is independent if fullscreen or windowed.
660Ti, 310.x or 313.09 same issue
Opensuse 11.4, 32 bit, KDE / KDM; problem exists independent if compsiting is on or not; also independent of vsync off or on
It happens only (recognizable) with 720p or higher.
P.S: as previously mentioned in another thread - i changed from a 460 GTX recently and havent seen the effect there with the 310.x drivers. Its more than a pity to see that regression with the newer card.
Pls feel free to ask me for some tests…
[update] have to correct myselfas i did a bit more testing:
- does only happen on some high res videos, but not found out about a pattern
- does NOT happen with mplayer using VDPAU (when playing the same DVD ISO with vlc using xv it happens)
