Game locks up computer on loading screens in linux

I’m playing on Linux and experiencing a suite of problems. The game starts off by not responding (works itself out if I wait), then there is a problems with textures in character select, but worst is freezing that I sometimes get when loading into a new area. It happens quite regularly and I think it might be related to how graphically intensive the previous or maybe next area is, since I notice it happening more when I am in an area where the game runs worse. Sadly it makes the game unplayable since when it freezes, it completely stops my computer from running and I have to manually shut it down and restart. The issue happened in both of the attached logs.
