Any help is appreciated. Thank >> you in advance:) > I see the same thing on my Sandybridge system. I've been seeing it since I first installed KMS code. Others suggestion I am infected by "The Matrix", but it's red, not green. They may appear in any window and I can often eliminate it by selecting the "infected" area and then de-selecting. Yours is the only other report I've seenof this problem. While I'd love to get this fixed, getting console mode back would be even nicer. I also occasionally get other artifacts like a few lines of test getting darker. I suspect it is being written to the screen twice with a single pixel offset, but I can't confirm. 9.1-Stable (r246004M) amd64 system. Sandybridge with no nVidia support card. Pure Intel GPU. ThinkPad T520. All xorg is from ports and this has happened since I installed the KMS support.. -- R. Kevin Oberman, Network Engineer E-mail: rkoberman@gmail.com
