SpMp platform

Windows

OS version

Additional information

Going to AppData\Local\spmp/preferences.json and removing "THEME_ENABLE_WINDOW_TRANSPARENCY":true,"THEME_WINDOW_BACKGROUND_OPACITY":0.8039031, fixes the issue.

I don't think this option should be visible unless it is supported in windows.
