Screen / Video artifacts and tearing

[da84tona]

First off, Just want to say thank you to all the chefs and forum members, when I discovered this place it was a Godsend. You all rock!

Now for the main point of my post, I am currently using Mighty Rom 4 on the Alltel network and I'm noticing intermittent video tearing / artifacts, sort of like the screen is offsetting itself and kinda flickering then it will go back to normal, (Its hard to explain )while navigating my touch pro. I tried reflashing other roms and still seem to have this problem that only started recently.

It seems to happen more frequently when the stylus is out of its holder, and it happens in landscape and portrait mode. Any suggestions?
Thanks!
