FYI: I tried 3.1b2 under Linux (RH5.2). I've been using 3.0. Also, I run the same application code on SGI and NT using corresponding OpenGL libraries. I noticed a rather bizarre color change anomaly while testing beta 2. The behavior does not exist under 3.0 or machine specific OpenGL libs. I am able to localize an area of my application that causes the behavior, but haven't yet found any glaring errors. The function in question is calling glMaterialfv. Building a Glut based test case is out of the question for me (my application is Tk/Tcl based and uses the Togl widget), but I will investigate further to see if I'm doing something strange that only becomes visible when using the Mesa beta. -- Gene Caldwell [EMAIL PROTECTED] _______________________________________________ Mesa-bug maillist - [EMAIL PROTECTED] http://lists.mesa3d.org/mailman/listinfo/mesa-bug _______________________________________________ Mesa-dev maillist - [EMAIL PROTECTED] http://lists.mesa3d.org/mailman/listinfo/mesa-dev
