I just updated to Start11 Version 1.39.1 on my PC running Windows 11 Pro Version 22H2 (OS Build 22621.1265). I am using the Windows 7 Style menu with the Windows 7 Style substyle. When I right-click on the Start Menu, on any item in the Start Menu, or on the Taskbar, the context menu displays with a black background. I first encountered this and reported it with Version 1.36.
My guess is that Start11 is now picking the background color based on the Default Windows Mode setting found in Settings > Personalization > Colors. As has been the case for some time, I have the overall Color Mode set to Custom and the Default Windows Mode set to Dark. For some reason, Microsoft requires those settings to enable the option to turn on Show Accent Color on Start and Taskbar. With those settings and Default App Mode set to Light, no other context menus show up with a black background.
I’d like to see Start11 display context menus for Start Menu items the way they were prior to Version 1.36, and as they were in Start 10, Start 8, and Windows 7 itself.
If the intent is to make a dark background an option, ideally it should be a configuration setting in Start11. Alternatively, if it is to be based on the Windows Personalization settings, it should only be put into effect if the overall Color Mode is set to Dark or the Default App Mode is set to Dark.
