I have a big problem in gtkradiant 1.5.0 with making Nexuiz maps; Each time I Control + Shift + Click select a brush an issue takes place in the viewfinder and all textures start being stretched like a reflection map on the surface depending on how I look at them. The only way to fix this issue is to deselect and reselect.

I looked all over google for how to fix this but couldn't find any solutions. Is anyone else experiencing this? Is it a video card driver issue or something of the sort? I'm using Windows XP SP2 and have an ATI Radeon X1300 / X1550 graphics card. In the picture below the right is the normal view while at the left my texture gets stretched once I select the brush and stretches / moves around when I look around.

gtk has a rendering error that causes it, try using the texturing tool as well as editing the shader or use another q3map2 like program compatible with nexuiz like netradiant.
