Segfault when .draw() is called on x64 Linux

[hunternet93]

I'm running Linux Mint 16 64-bit (similar to latest Ubuntu) and I get a segmentation fault when anything tries to write to the screen, I tested several demos. I have a hybrid Intel/AMD graphics card (Radeon 7690M) using AMD's proprietary FGLRX drivers. I installed Pillow and mesa-utils-extra from apt-get.

Here's a backtrace from the command "python3 Minimal.py"

Solved by switching to the open source Radeon driver, demos run fine now.

Great, thanks for the info. The libEGL warning presumably related.
