Vim intermittently fails to render text across the fill width of the window when invoked using its GTK GUI. This mostly happens after scrolling but can happen immediately when a file is opened. I've attached a screen shot of the corruption. Note the truncated text at the top of the screen and the fully rendered text at the bottom.

This bug looks like it's a problem between gvim and X somehow as dragging another window across the area that vim has failed to render then moving it away again causes it to render the missing text. However in the cases where I get corruption it happens again when I scroll.

Some additional information.

I've compiled an upstream vim from the 7.2 sources and this exhibits exactly the same problem (once FORTIFY_SOURCE is switched off in order to actually get it to run) I've not tried the latest svn yet.

[Paul Gotch (paulg-chiark)]

The tip of svn, ie vim 7.2.367 also suffers from this problem.

For reference my video card is ATI Technologies Inc RV380 [Radeon X600 (PCIE)] and it is using the "radeon" driver.

[Paul Gotch (paulg-chiark)]

This is definitely related to the the graphics driver. Switching to

RV710 [Radeon HD 4550] rev 0

has made the problem go away.
