Lack of S3TC support in video driver, most likely:

force_s3tc_enable=true playonlinux
This caused the game to crash while loading, and when I hit "reconnect", it told me that it could not connect to the pvp.net server. When I disabled force_s3tc_enable, the game reverted back to its original state, where I could not see the game, but the UI was functional. Any suggestions?
(I am using Mint 17 Cinamon 64 bit)
Edit: I installed libtxc-dxtn0, but I still get the black screen glitch.
