--- Comment #26 from Hajo Krabbenhöft bugzilla+winehq.org@hajo.me --- I just tried to run the newest iTunes 12.13.2.3 (x32) inside a Windows 10 64-bit in CrossOver 23.7.1, which ships with Wine 8.0.1.
My unscientific guess is that the black screen issue is somehow related to memory alignment and/or buffer re-use. I'm basing this guess on the observation that if I drag the window and resize it in the X direction, what I see toggles between a fully black screen, a black screen with some white text and a good-looking screen with missing text. At also appears that larger window widths have a higher chance of showing the regular UI without text while smaller window widths have a higher chance of showing the black screen.
I have attached 3 screenshots to illustrate.
