I'm trying to run Wurm on a Gentoo Linux desktop with a Radeon R9 950 using the open source drivers. Every time I try to start Wurm it crashes immediately on trying to switch into 3D mode: http://pastebin.com/7KrDUZGg I'm not an expert at reading those things, buit it looks to me like some library is trying to call a function in another library with the wrong arguments - maybe due to an API version mismatch or unimplemented features. I've tried various combination of llvm/libdrm/mesa versions and none of them seem to resolve the error.
