running into a possible nvidia driver bug on linux:
anyone who can use pbuffers in linux, try this:
with the pbuffer context current (and separate from the main context), execute a glRasterPos and see if your app crashes.
this is with the 6629 drivers
here’s another one:
try to call glxMakeContextCurrent with the pbuffer set as the draw buffer and the main buffer as the read buffer and you get a crash with a glx BadDrawable error.
i want to verify this happens for others before reporting the bug…
