Dark Mode title bar still white in Windows 11



  • Fringe case for now, but the title bar isn’t going dark for me on Windows 11. Dark mode is enabled at the system level.

    Wait, Windows 11?! You’ve gotten a copy already?! You are brave.

    For me, with Windows 10, that’s what it looks like when I first change to Dark Mode from the Settings > Preferences. Then I read the instructions on Settings > Preferences > Dark Mode, which tells me to restart Notepad++ after making the change. When I follow the instructions, then the title bar goes dark after the restart.

    I doubt the developers have a copy of Windows 11 to test on. So please make sure you are following the correct sequence

    Restarted Notepad++, then Windows to no avail. I assume it’s just an incompatibility for now, but figured I’d report the findings regardless.



  • @MilkManEX ,

    Could you share your ?-menu’s Debug Info? The information in there will help the developers look into it, once they have a Windows 11 environment where they can debug. Unfortunately, until they have that environment, it will probably be difficult to replicate the problem on their end, and will likely not be able to figure out how to fix it.

    (Also, while this Forum is good for looking for help or workarounds, or confirmation from other users, it doesn’t get the developers’ attention for bugs. We have a FAQ explaining how to report bugs… though I’m not sure how much good it will do until you at least get corroboration from another Win11 early-adopter.)



  • Debug info as follows:

    Notepad++ v8.1.1 (64-bit)
    Build time : Jul 1 2021 - 14:10:53
    Path : C:\Program Files\Notepad++\notepad++.exe
    Command Line :
    Admin mode : OFF
    Local Conf mode : OFF
    Cloud Config : OFF
    OS Name : Windows 10 Pro (64-bit)
    OS Version : 2009
    OS Build : 22000.51
    Current ANSI codepage : 1252
    Plugins : mimeTools.dll NppConverter.dll NppExport.dll



  • The title bar is mostly controlled by OS itself.
    You can customize it using Settings > Personalization > Colors > Choose your accent color.
    I am sure something similar exists in Windows 11.

    Then it can look like this:

    You can chose a darker color.



  • Interestingly, if I force a color on the title bar, it shows up in Notepad++ when the window is active:

    However, if the window is in the background, it’s still defaulting to white:

    Windows 11 still has some features, like Task Manager, that are incompatible with dark mode and exhibit this same behavior. Takes the color if you force it, but stays white when not in focus. I assume Notepad++ is, for whatever reason, being treated by Windows the same way.

    Yes, it seems Win32 apps (like Task Manager or Notepad++) are treated differently than latest UWP or similar apps (like Windows Settings window). The latter can also have transparency on the title bar.
