Does the bug still occur with wine-7.0-rc5?
I can't test it because there is another bug in the way. The game's speed cap is lifted in Deltarune and Undertale, making it as much as 2x faster and harder to play in general. So far the only option I had was to try and use a fan made Linux port, which works. If this bug of the speed cap can be fixed, we can go back to this one but for all effects, it does.
