which version of wine are you using ? There is a problem on the newest release (wine 2.2) that i am currently fixing that seem pretty similar to your first screenshot.

As for the second one, that would simply be because your vm did not have hardware accelerated "card" setup (or driver not properly installed).

If you are on wine 2.2 but do not actually need 2.2, you could lookup how to downgrade your wine version on your linux distributions, in some cases its pretty simple and downgrading to wine 1.9.21 would fix it.

If you prefer direct support on this, hop on our discord channel and private message me about it. You can find our discord channel link in the community menu.

The issue should be fixed soon, but that kind of problem can be very tricky to trackdown and i am still uncertain if its a problem in our code, or a regression in wine code.

Thanks so much for the quick reply!

I'm afraid I'm having a far sillier problem. I don't even have wine 1.8, the version I've been using (default for Ubuntu, I guess?) is apparently 1.7.53.

Oops.

Installed 1.8 with the fancy wine-team's PPA, and now, it all seems to be working fine. Thanks, and sorry for not checking first D:

no problems at all, glad you got it working.

When you run Star Sonata, are you writing all the error messages to /dev/null?
