--- Comment #2 from Vidar Haarr vhaarr+wine@gmail.com --- I've tested battle.net with build https://dev.wine-staging.com/builder/group/433/download/ which is built from https://github.com/wine-staging/wine-staging/commit/4f315f2a1025788885f85dbf... and Battle.net seems to be working OK - I can start SC2.
I have not tested Steam, so I am not closing the bug - Zebediah can you confirm and close if appropriate? Thank you.
And thanks to Alistair for the fix :-)
