Have been evaluating the latest nvidia beta drivers (180.06, 64 bit) and they
seem to have fixed the screen artefacts that plagued KDE 4. I'm not seeing any
issues with task bar glyph corruption etc.
However :) On my GF6100 I was seeing bad text corruption, particularly with
Italic text. Apparently its due to the GlyphCache been enabled for the 6 & 7
series of cards for the first time. The fix is to either disable the glyph
cache:
nvidia-settings -a GlyphCache=0
Which apparently will impact performance, though I didn't see any difference,
or Disable sub-pixel hinting in the anti-aliasing settings.
Both worked, I'm quite pleased with the overall results.
The drives can be downloaded here:

64 Bit

Additionally they include VDPAU - NVidia new API for accelerating video
playback (PurevideHD for linux basically). I've seen very good reviews and
benchmarks on this, but you need a 8 Series card or better and patches to
mplayer to use it. No doubt support for this will work its way into xine (and
hence kaffine), MythTV etc.
