OpenGL error when running Battle.net

[PastyPilgrim]

With some tinkering I've got battle.net working via wine (it used to crash after 3 seconds everytime) and have successfully installed hearthstone through battle.net. Yet, running Hearthstone results in an odd set of behaviors: I'm forced into the workstation/window swap interface and a new hearthstone window pops up, but it is a screenshot of my desktop with the battle.net client open. With this error.

Thanks for any help guys.
