gvim unreadable text
 

I'm having a strange problem with gvim. I've installed Slackware on 4 computers now, and this latest one is the first I've seen this issue on. I use the command line for almost everything, and only use gvim in Firefox with Vimperator. So it isn't something I use all the time, but when I need it I really need it. Using textboxes (like, you know, on LQ) is starting to drive me up the wall :)

Anyway, when I load gvim (through Vimperator or other means) the text is unreadable. It does seem to become readable after it gets covered by another window, but as I type, the new text is unreadable again. Attached is a screenshot, of this post. Any ideas?

Thanks!

And, actually, I'm seeing similar behaviour in Gimp. Attached is a second screenshot. The weird lines seem to appear and disappear when the mouse rolls over the area. I don't use very many GUI programs, just Firefox for the most part (which isn't displaying this behaviour). So, this could be a general X issue, or perhaps a WM issue. I use Awesome if it's relevant.

Maybe it's your graphics card. I had similar issues for a while, certain programs would have distortion, while others were fine. Put another card in and the problems disappeared.
