I have my third monitor working now with the GLINT driver but I've noticed a strange screen corruption bug. It seems often i end up with purple bits on the screen. It seems to be due to some specific optimization as it affects specific areas of specific windows repeatably. And it seems to be sensitive to the precise location on the screen as sometimes simply moving the window a few pixels over makes it not go away. For example in the gimp the little triangle in the ruler that moves with the mouse pointer leaves purple turds behind as it moves around. Also, the icons in the gimp toolbox have purple bits in them. And the scroll bars in gnomeicu message windows are purple. Here are a couple screenshots -- one of them is actually of a gimp window with a screenshot of a gimp toolbox inside it.

Here is a couple interesting excerpts from the XFree86 log. The last time I tried to post an entire XFree86 log it got bounced due to being too large. ...
