nv driver: tearing artefacts

[Harald Dunkel <harald.dunkel@t-online.de>]

Hi folks,

I got a Gainward Pro/660 TV/DVI (NVidia FX5200) and a Dell 2000FP
(1600x1200 TFT, 60Hz, 56.0-75.0kHz). Driver is nv.o, XFree86 is
the most recent 4.3.


Using xv (e.g. xine) in fullscreen mode I see a lot of short
horizontal lines flickering all over the screen. AFAIK these
are called "tearing artefacts", but I am not sure about the
terminology. Plus there are some noisy dots at the left edge
of the screen.

This distortion goes away, if I either

- use xshm instead of xv
- don't use the full screen (using a maxsize window with a small
  frame around it is sufficient)
- use the analog port of the same monitor instead of DVI
- use M$ Windows

Reducing the screen size to 1280x1024 or using different
mode lines (e.g.
Modeline "1600x1200"  162.00  1600 1664 1856 2160  1200 1201 1204 1250
Modeline "1600x1200"  154.75  1600 1616 1968 2208  1200 1200 1211 1253
) did not help.


Any idea how to fix this? Is there an "experimental experimental"
version I could try?
