--- Comment #9 from Zel Uneec zculek@gmail.com --- Hello Olivier,
Thank you for your interest in this!
Yes, this is not related to HD graphics being enabled or not. I can enable HD graphics without problems and the difference between HD and SD is pretty clear - SD is 4:3 with 800x600 resolution while HD is widescreen with higher resolutions, more clear graphics, sprites, etc. It's kinda like the HD resolution is not properly applied or sth. like that, don't know how to describe it different way. You can check some of the screenshots I attached and I can attach an SD screenshot as well, if you'd like to see the difference, but you'll be able to check it yourself in the game too.
There's also this bug, which I thinks is somehow related, as both of proper graphics and RTL stopped working for me and most of the community with Wine versions >5.6 - https://bugs.winehq.org/show_bug.cgi?id=46624 Perhaps you'll get some good info and answers there.
Also, one thing to mention - people were usually using wine-staging for Battle.net and Brood War, as it had some needed patches which weren't present in the stable.
Let me know if you need any additional information.
