MU4 opens to white screen on opening

• Apr 16, 2023 - 15:40

When I open MU4, sometimes it opens the way it should, but most of the time it becomes a plain white window. If I try to open a score directly and it's an old MU3 file, it's still a white window but asked to save the file when I try to close.

This is after troubleshooting an issue with the program not getting past the loading screen. Root cause was something to do with missing a playback device.

Went to grab a screenshot and learned more: If the window is full-screen when I open MU4, the window is white. When I make the window smaller, it loads. Still a bug, but at least I can work on stuff now.

If I maximize that window again, it's loaded just fine.

Is there any plan to fix this egregious error in programming anytime in the near future? This makes this program total junk. What should I do woth the many dozens of scores I've created?
