On some maps I get a messed up problem. The maps are always tower or RR maps. Never had the problem yet on any other kind. But it does not affect all of them so I don't know what could be the problem. Looked through the forums did not see a topic talking about what I see. The red lines are what the map looks like when I join and then they start to blur and superimpose so they look like the black lines only 100s of them and all except the actual line is slightly lighter. Even my worms, ropes, etc start to leave trails behind them when they move. I tried the wormkit color fix, and all the color fixes I saw in the FAQ. Tried compatibility changes, tried resolution changes. Nothing has helped. Like I said have no problems with many of the big color maps but with quite a few of them I do. The number of colors also does not seem to define when it messes up or not.

I am running Win 7 64bit Ultimate. ATI 4830 card.

There was an issue similar to what you describe which was introduced in 3.6.30.0, but that was fixed in 3.6.31.0.

THanks that solved the problem.
