Screen corruption / server lockup running qgis

[David Bronaugh]

Hi,

I just tried running qgis (GIS application). When I tried loading in a 
sizeable polygon, the X server fell on its ass (the screen immediately 
became totally corrupted -- nothing was legible -- and the mouse cursor 
froze). Nothing appeared in the log.

Just for fun, I tried it within Xnest -- the same problem was observed.

I'm running Intel 2.1.0, on Xorg 1.3.0.
