I'm using the precompiled DRI/OpenGL package of VMD 1.7.1 on a RH
Linux 7.2 box equipped with a Geforce 3 card. The build of the NVidia
1.0 drivers is 2802 and the kernel is stock (Tosatti) 2.4.18. The
graphics window of VMD works, but sometimes gets thrashed or worse
when the window is resized. Resizing the window right after launch,
before any molecules are loaded, thrashes the 3d display every time,
but usually this can be recovered by resizing the window again. During
a session, when there are molecules in the 3d window, resize
operations seem to randomly either work, thrash the window until the
next resize, crash VMD, hang X or even crash the whole system. VMD
1.7.0 suffers from the same problems.

The same NVidia driver seem to be ok on a Geforce 1 card, although I
only tested very briefly. I have seen thrashing of some windows when
using other OpenGL applications with the 2802 drivers and Geforce 3,
but never system crashes.

Anyone else with experiences of 1.7.1 and build 2802 of NVidia
drivers?

Cheers,
