I've got a pixel that's doing something I haven't seen before. Using LCD Test, which goes between different full-screen colors, every pixel on my display seems perfect. However, when I go back and have several windows, etc open, one pixel appears to be stuck right in the middle of the screen, 2/3 of the way up.
If I have no windows or anything open it's fine, but when I open a small window, keeping it's height well below that of the bad pixel and move it beneath that pixel, it changes colors. If I move the window over to the side so that it isn't underneath the pixel it goes back to normal - when I move the window back into that pixel's row, it changes back. It's getting really annoying...
Anyway, I know they probably won't do anything since it's one pixel (but of course right in the middle of the damn screen), but I just wonder what's going on to make it not just stay stuck. I'm not even moving the window over the actual pixel to make it switch back and forth, but under it, and it still changes. Anyone seen this behaviour before?
