gvim display corruption

Sometimes a small gvim window renders fine for some time. Maximizing it (1900x1200 resolution) triggers the problem quickly. And sometimes restoring the original size also removes the display artifacts. Sometimes, sometimes not.

I am able to recreate consistently with visual effects (compiz) enabled. With visual effects disabled the problem seems to go away. Hope that information helps, will be glad to provide other troubleshooting if needed.

I see the same problem here.
The same problem affect OpenOffice when its antialiasing is enabled.

I tried playing with the "workarounds" configuration of compiz, which don't fix it.

Switching to metacity fix it.

I am also experiencing this problem. It only happens with effects turned on under System, Preferences, Appearance, Visual Effects. Minimizing or Maximizing the window will wipe away all the corrupted lines, but moving the view or scrolling the cursor will corrupt any text that is new. Sometimes minimizing will fix the problem and it will not re-occur until a new file is opened.

Same here. I've just upgraded to 10.10, switched to compiz and encountered this bug. Below is some relevant info about my system. Let me know if anything else is needed:

My nvidia card:
00:05.0 VGA compatible controller: nVidia Corporation C51PV [GeForce 6150] (rev a2)

My installed nvidia packages:
ii nvidia-173-modaliases 173.14.28-0ubuntu1 Modaliases for the NVIDIA binary X.Org driver
ii nvidia-96-modaliases 96.43.18-0ubuntu1 Modaliases for the NVIDIA binary X.Org driver
ii nvidia-common 0.2.24 Find obsolete NVIDIA drivers
ii nvidia-current 260.19.06-0ubuntu1 NVIDIA binary Xorg driver, kernel module and VDPAU library

You can work around this issue by setting

  set ttyscroll=0

in your .vimrc

Happens to me with gvim+compiz+nvidia as well.
Fixes mentioned in duplicate like changing font rendering does not help.

Workaround: change the font.

e.g. add to ~/.vimrc
set guifont=liberationmono

Kiwi, you're brilliant! set ttyscroll=0 worked for me, and I don't see any of the other symptoms noted in the "duplicate".
I should mention I'm running Nvidia on 10.04 with twin screens. When I was running kubuntu I saw this problem in Claws, so I switched to Gnome, and it cleared up everywhere except for gvim.
