  1. This bug appeared when one monitor was set to 125% scale and the other 100%, setting both monitors to 125% fixed it.

  2. Thanks commenter Matty B – your solution worked for me. I hope I don’t have to keep doing it and it remains a permanent fix 😉

  3. Reload the graphics using (taken from the Microsoft known issues page):
    Ctrl + Shift + Win Key + B worked

  4. Same as others no dwm.exe or “intel graphics settings” It happens almost every day. Starts fine and then mid morning it pops up. If I click to close a window, it closes the one behind it which I can’t even see until it flashes for a second and then closes. I have to restart my computer to regain the whole screen. Very annoying.

  5. Nothing comes up in a search in my control panel for “intel graphics settings”
    2nd option worked.
    Does this work for good, or is it something I’ll need to do everyday?

  6. Pressing F11 to “enter full screen” and then back again to “exit full screen” does the trick on mine, which has an NVIDIA card too.

  7. Nothing comes up in a search in my control panel for “intel graphics settings” and there is no dwm.exe in my task manager search.
    Hmm… any other ideas?

  8. Fix 1: I’m not using Intel Graphic Card, but NVIDIA GTX 1660 Ti.
    Fix 2: it was my first try, but nothing happened, it returns with the bug.

    In my case, the top of maximized windows may be buggy, not repainting and ignoring clicks. All clicks go to the background windows.
