I managed to get Wine and Winetricks installed successfully, and even successfully installed the Blizzard app! I followed this guide: https://linuxconfig.org/how-to-install-blizzard-battle-net-app-on-ubuntu-18-04-bionic-beaver-linux
At the bottom of the guide, it says something about HotS requiring dx9 because dx11 isn't supported yet. I have no idea what that means, and thought I'd try running it anyways. I figured it wouldn't work but wanted to check, and of course it didn't work. I don't even know where to start as far as running it with "special launch time flags" or even what that means or how to start learning about this stuff. Any help getting Heroes of the Storm running would be appreciated.
EDIT: I tried different drivers and that didn't help at all. I went from the default open source drivers to the Nvidia drivers.
