--- Comment #17 from anthirian@protonmail.com --- For me wine 6 combined with iTunes 12.9.0.167 does not show the black screen. I have a clean wine prefix and only installed iTunes so far, without any further configuration of settings or extra dlls. For the 12.10.x versions every single one I've tried shows the black window. As others have mentioned this is likely due to the fact that iTunes tries to autodetect light or dark mode, and falls back to (very) dark mode.
$ wine --version wine-6.0
