Whenever I load up a map to play in RRT3, be it sandbox, campaign, scenario or even the map editor, I have this grid like glitch appear across the map. It doesn't really do anything gameplay wise, I can place buildings on it, and even have trains run across it, but it is distracting and annoying to see when I have zoomed out to see the whole map, and it is visible if I zoom in too.

I have tried adjusting the resolution of the game, as well as running it in windowed mode and as a administrator. I've tried turning the graphics settings to both ultra low and ultra high, and have applied the 1.06 patch as well as the Blurry texture fix and the Vista/Win7 Fix from hawkdawg.com

I've searched across the internet and I seem to be the only one with this issue. I tried to take screenshots of the issue but all that showed up was a black screen.

The "G" key normally toggles a grid overlay on the map. Did you try it to see what happens in your case?

Unfortunately this is separate from the grid overlay, and will stay visible even if I turn on the grid overlay or even other overlays like cargo supply. Do you know what might be causing the screenshots to turn up black? Because it would really help if I could give a visual of this glitch.

RT3 screenshots contain tga alpha/transparencies. These appear to be blank/unused. Some image viewers need to be configured to not display those before the real colors are visible.

Aha! Now I can see things! Here's some screenshots of the issue I'm facing.

Note: had to convert to 16-bit, but glitch is still visible. The glitch only seems to effect the map itself, not anything placed on the map like buildings and trees.
