Some windows 10 users reported that when they maximised a window of any application like browser (Chrome,IE etc) or a program , it shows an empty or black space at the top. The rest screen looks OK, and behaves normal. This thing is bugging many users and if you happen to be one among them, then here is the fix to solve the problem.

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

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.

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?
Renato says
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.
Will says

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?
Thanks

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.
