FINALLY! someone who's experiencing a problem similar to mine. well, it sounds similar, anyway. if you ever figure out what is causing it let me know.
i have an app that uses a GL screen in an xforms window. the first time it runs, the GL screen works fine, the second time and each time thereafter, until i restart X. i've run it on GeForce 2, 3, and 4s with RH 7.3 and 7.2. and several versions of X.
i spent days trying to find out what the problem was, and the only conclusion i got to was that when i downgraded to 1541, it worked. everything newer than that (2802, 2880, 2960, 3123) did the same thing.
it seemed no one else was having this trouble. i wonder if it might have something to do with the forms we use with the GL screens.
please let me know if you figure it out. and email me at firstname.lastname@example.org
. and i will let you know if i figure anything out.
