This is what I’m getting with gtx 660 ti all last drivers !!!
This line appears almost everytime I play videos. I’ve tried changing drivers,OS,bios, etc,nothing works!

Change Video Quality to 720p or 1080p
This what I get and it’s fing annoying already. NO such things in windows 7. I’m very confident it’s nvidia linux driver that craps so bad.
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)
I’ve tried unity, gnome shell and cinnnamon.
I’ve noticed it starts happening when graphics and memory clocks drop to 324 Mhz
I see that line and some other small lines like that when switching web pages.
My specs:
linux mint 14 cinnamon
i7 3930k
rampage iv gene
ddr3 16gb
EVGA GeForce GTX 660 Ti FTW Signature 2
psu corsair 850W
just did a quick test on the same youtube posted above with 1080p set and “Prefer Maximum Performance” locked to a higher clock and didn’t see any lines and artifacts.
Update: tested it - Flash is ok if set powermizer level to "prefer maximum performance, BUT this does NOT solve the problem in VLC (2.0.5) Player watching a DVD. It is there same behaviour, horizontal line is there not always but especially when much motion in the picture, e.g. camera panning or a scene with people acting very vivid (e.g. audience of a football game).
Does not happen if mplayer + VDPAU same DVD, regardless of powermizer level.
Again, this did not happen with same driver with my 460 GTX, so it must be related to Keppler, and a more underlying problem than just clock level.
I tested on all available drivers for 660Ti (Gainward Phantom) 304.x, 310.x, 313.09- same behaviour
have to correct myself again - happen also with mplayer using VDPAU - just less.Found an example i can even reproduce then. Powermizer level “prefer max perf” helps here too (not for vlc as mentioned), but my guts feeling is it’s related to the memory interface and the screen display timing.
Once recognized, it is very annoying bug. And so a pitty as I just get less from the newer card i bought.
I can confirm this with a Gigabyte 660 Ti, 310.19 driver, xorg-server-1.13.1. It didn’t happen with my old GTX 275, started only after upgrading. Happens only with xvideo output, vdpau is fine. I noticed it with mplayer, mplayer2 and VLC. Setting performance level doesn’t help. Flash works fine for me, but that’s probably because I’ve turned on hardware rendering, which I guess uses VDPAU.
I also noticed it doesn’t happen if I have KWin compositor running and the video plays in a window.
Two, did you pay for a support contract? Maybe a weird question, but it’s nevertheless accurate. Linux support is unofficial (note how we’re here at the “devzone” instead of the main forums), so there’s no guarantee you’ll receive an answer.
