Anyhow, can you try with 'GLWIN_NO_WGL_EXTENSIONS=1 XWin -wgl -multiwindow'
Thanks. I did this and it worked. However, for a particular paraview
dataset that I happened to have lying around it is slower than direct
rendering by a factor of about 2. That may be related to the fact
that this particular scene has wiggly tubes with structure too small
to show on the screen, so there is a high ratio of data to things that
actually get displayed. For the same scene, unaccelerated indirect
rendering is much slower than accelerated, perhaps by a factor of 10.
So when you can't use direct rendering, acceleration is a big help.
Once I say -wgl, direct rendering no longer works. That is, if I
don't set LIBGL_ALWAYS_INDIRECT, then I get a long (infinite?)
sequence of errors like this:
X Error: BadMatch (invalid parameter attributes) 8
Major opcode: 73 (X_GetImage)
Resource id: 0xa0039a
I attach my XWin.0.log from a test in which I first succeeded with
LIBGL_ALWAYS_INDIRECT and then got the error above without it.
