--- Comment #13 from David Brooks skade88@gmail.com --- This is not a bug in Wine. This is a lack of the proper fonts. Without the proper fonts installed the battle.net application does not have the required font to display the text in the pulldown box so the pulldown box is not populated.
On Ubuntu 16.04 I was able to resolve the pulldown box issue by downloading the fonts and building the font cache.
Downoload the fonts sudo apt-get install ttf-mscorefonts-installer
Build the font cache sudo fc-cache -f -v
Now launch your battle.net application and you will be able to select your region.
