#182 Crash when loading PDB with llvmpipe

[Thomas Linsky]

This problem occurs with Pymol 1.7.2.1 and 1.8.3.3 in linux, using the llvmpipe graphics driver. This is used by default on Ubuntu VirtualBox virtual machines. Pymol 1.4 does not have this issue and works great. The expected behavior is that the PDB would load and the structure would display properly. It is expected that using llvmpipe should be slower than native 3D accelleration, but it should still work.

Steps to reproduce:
1) In linux, set up a graphical environment that uses llvmpipe as the driver. One easy way to do this is to install ubuntu into a VirtualBox virtual machine and then install pymol.
2) Start pymol
3) Type 'fetch XXXX', where XXXX is any PDB id
4) Crash occurs after pdb is downloaded

Does it work for you if you disable shaders?

1) Start pymol
2) Type: set use_shaders, 0
3) Type: fetch XXXX

That fixes the issue! Thank you!
