           Version: 1.2-nightly
        OS/Version: Windows 2000
            Status: NEW
          Severity: normal
          Priority: P2

This bug is actually for WindowsXP, buts its not limited to WindowsXP the same 
thing happens in Windows 2000 Pro as well

Ok this bug occurs on all of the ATI Radeon 8500 drivers i have tryed, i'm not 
sure if it is only on the 8500 it maybe on some of the other Radeons too.

The bug is basically a corrupting of the Map view and the 3D View. But... its 
effected by several other things it seems. This bug doesn't occur in Q3Radiant 
or WolfRadiant unless i place a light entity on my map.

Things that don't effect it, i've spent serval hours tweaking my Radeon to see 
if my various driver settings effect what happens and they don't, i have also 
played around with the setting of GTKRadiant as well but to no effect.

I have supplyed some pictures if they attached correctly!

First of all the bug (shown in picture 1) for some reason the top left quater 
of the map view becomes corrupted as does the 3D View.

Once this happens it seems to sort of return to normal by selecting a brush and 
manipulating it in some way e.g vertex manipulation etc... but if y move to 
look at a different part of a map with returns to the corrupted look again.

The other thing is the zooming issue with the 3D view dissapears and the YZ and 
XZ views the grid and everything else dissapears (see picture 2) This is in the 
worldcraft style layout

Now if you zoom out on the XY view the whole returns and as long as the XY view 
is zoomed out then the problem never occurs (see picture3). In the Quad view 
the other bug doesn't happen.

I hope this has been of some help i'll gladly test anything you produce please 
let me know if theres anyother information you need and i'll try and supply it
