Ripples that resemble circular wavelets when a stone has been thrown in a lake, appear on my screen when I use a pen tablet. It happens with Photoshop elements, with Gimp and with MS Paint. I've tried everything to resolve it, but without success. Googling the problem shows this is quite widespread, with many requests for a remedy. I'm using Vista.
There is a Mouse Setting that has a very similar effect. It is usually used to highlight the position of the Pointer in visually challenging backgrounds.
Could your problem be something similar
