Hi,
the use of the OpenGL API within your software leads to a complete workstation freeze using fglrx driver version 8.982. The workstation does not accept any mouse or keyboard commands only hard reset is possible.
System: Linux (RHEL 6.1, Kernel: 2.6.32-279.el6.x86_64) workstation
Hardware: AMD FirePro V7900 (ATI FireGL) using driver version 8.982 (fglrx64_p_i_c-8.982.8.1-1.x86_64).

We still do not know what exactly leads to this problem or how we can debug it. Any ideas?
Thank you
