--- Comment #22 from Denilson Sá denilsonsa@gmail.com --- Perhaps indeed XComposite wasn't compiled into my self-built Wine version, for whatever reason. Because I just tried again with the `wine-10.13` binary from Manjaro, and it worked fine this time.
So, given I cannot reproduce the problem anymore, and given that the commit mentioned in comment #11 are supposed to fix it, I think it's safe to close this issue.
Sorry for the noise, I honestly wanted to help. And thank you very much for maintaining Wine!
