HELP: Terrible Image Glitches when Dragging and Zooming

Duplicating elements when I drag and zoom with the mouse and scroll wheel. The processes themselves aren't very slow. Already reduced view radius and some other stuff. What do you guys suggest?

I have not seen this before. Is this your first time using MT? Have you had any recent updates like Windows updating your video card? What version of MT are you using?

Update your video card drivers.

Which version of MT are you using, and most importantly, which launcher ?

I have an issue that is similar, when I use wolph42's launcher for MT b90. It seems to work for others without issue, so I have no idea what's different about my PC that messes it up.
Clyde's alternative launcher listed here works perfectly for me and eliminates the graphic issues. I dont know if you are having the same problem, but if you're using wolph42's launcher, it's worth trying.

I agree it is strange. I fully expect it's something about my setup, rather than a problem with the launcher, but it's possible someone else has the same issue which is why I mention it.

It's more likely due to graphics drivers or how java interacts with direct draw. Reinstalling both would probably fix the problem. I was thinking if using an older MT version that's not compatible with java7 would cause issues as well.

I don't want to hog the OPs thread in case their problem isn't the same as mine (but i do see graphic glitches like the OPs - it seems like parts of the screen are not being erased, and get drawn multiple times). I've updated the thread I initially reported my issue in, here.
