Doing some worldbuildering, when i hit the reveal tile button, bizarre things happen to the graphics. It seems different every time, i mean REALLY different. The first time it was just glowing purple coastal tiles, quit, restart, then something totally different happens; blacked out tiles, blurring, static, you name it. I can save the game and quit out, then reload and everything is fine, so no point in posting a save game, but here's some screenshots:

1st one, the whole screen became a big minimap, notice the giant units:

Then the same game when i exited WB:

And one more to show the randomness:

The only "mod" i have on is i changed my GolobalDefines XML to have 5% tech slider increments, not 10%, but i'd be real surprised if that was the culprit, and the version is BTS 3.19

Again, the saves come out fine, so i can just save the game and quit to desktop, reload and the changes i made in worldbuilder are still there, everything is good. And since all i'm doing is unrevealing all tiles for a civ i've moved, it's not a real issue since i can do that, save, and quit even while the graphics are all screwy, but is is annoying.

I've been running CIV on this computer for a few months with no problems, all graphic options on high detail, can run huge maps through the modern age with no real lag, so i don't think it's a spec thing. I have a 3.4GHz Pentium 4, 2GB of RAM, and a Nvidia GE Force 9500 GT.
Never had any issues with the reveal tile mode before (on this machine), any ideas?
 
Looks to me like a graphics card issue, though I'm no expert on this. Is your graphics card running at a safe temperature? Does this problem occur after a cold start of the computer at the coldest time of day?
 
I can't remember exactly when it was, it actually seems to have cleared itself up, but that would make alot of sense. I'm in southern california so hot october days are fairly common, and i often leave my computer on for extended stretches downloading various things.
Thanks alot, now if it happens again i'll have something to try.
