My OSG App renders to two screens (:0.0 & :0.1) of Linux system. If I
use an OcclusionQueryNode as my root, it crashes in this configuration.
First I get these messages:
Warning: detected OpenGL error 'invalid operation' after RenderBin::draw(,)
Warning: detected OpenGL error 'invalid operation'
Then a series of these:
Warning: detected OpenGL error 'invalid operation' at start of
State::apply()
Then a crash:
*** glibc detected *** ./app.bin: malloc(): memory corruption (fast):
0x00002aaab0190e66 ***
======= Backtrace: =========
/lib64/libc.so.6[0x3a0f8725e0]
/lib64/libc.so.6(__libc_malloc+0x7d)[0x3a0f872e8d]
/usr/lib64/libGLcore.so.1[0x3488fd8114]
I assume that I need separate instances per GL context to make this
work, but I am looking for advice as to how to implement?
Thanks,
Todd
