    Blank area at top of some programs when displayed in Maximized mode


    I asked this question back on July 2020, but have updated it and am reposting in hopes that someone knows a solution. Others are experiencing the same problem. The problem manifests itself as a blank area at the top of a maximized window. It occurs Only for certain programs (Notepad, Intel Graphics, Thunderbird, Firefox, Macro Exchange Pro32, VLC Media Player, Irfanview)Not for other programs (Word, Excel, Outlook, Powerpoint, Notepad++, PDFXchange Editor, Jarte, Mathcad, Visual Studio, Macrium Reflect)Only when the window is displayed in Maximized mode on whichever monitor is designated as primary on a dual-monitor system When it occurs, clicking on the program's menu items does nothing, and if, for example, the X at the top right of the screen is clicked, it closes not the affected program, but rather any program underneath it. The only way I've found to cure the problem temporarily is to reboot the computer. How long it takes before the problem recurs is variable. For example, I was free of the problem for over a month until 2 days ago. Now it's occurred 3 times in the span of 2 days. I've seen various suggestions for curing the problem, but none have worked. For example, one person suggested using Task Manager to "end task" of dwm.exe. This works for an already-opened program, but if the program is closed and reopened the problem comes back. This problem has been plaguing me (and others with dual monitors) for over a year. Any suggestions? System: Windows 10 Home 2009 64-bit; Intel Graphics 630 card [I wanted to reduce the size of these screenshots & display them side-by-side, but double-clicking them does not bring up a screen for adjusting size, as I was told. If someone can tell me how, I'll reduce them.] Windowed_________________________________________________________________________Maximized

    Blank area at top of maximized windows in dual-monitor system

    When running certain programs in my Windows 10 v. 1909 system with two monitors, sometimes a window displayed full-screen on one monitor (in my case, the one interfaced via the VGA port) will have a ~1" blank area at the top of the screen right below the title bar. (See the screenshot below.) From this point on, the system behaves as if that area of the window, as well as the title bar, is not there. For example, clicking the close "X" or the restore down icon at the top right of the screen will instead close or restore down any full-screen program that is underneath the problem one. Clicking areas or buttons below the blank area may or may not do anything. The problem occurs only if the window is maximized; a "normal" window, even if almost the same size as a maximized one, is not affected.

    Once the problem occurs, some but not all other programs, both 32-bit and 64-bit, also become infected. However the problem always seems to start with Mozilla Thunderbird. Closing down and restarting the programs doesn't help. The only way I've found to semi-permanently cure the problem is to reboot, at which point things will be fine for the next few hours or days until they aren't.

    Some programs that *are* affected: Thunderbird, Firefox, Notepad, Macro Exchange Pro32, VLC Media Player, Irfanview

    Some programs that are *not* affected: Word, Excel, Outlook, Powerpoint, Notepad++, PDFXchange Editor, Jarte, Mathcad, Visual Studio, Macrium Reflect

    I'm posting this problem both here and in a Mozilla forum, as I don't know if the cause is Windows 10 (it didn't happen with Windows 7) or Thunderbird, or some combination of the two.

    Update: Since posting, I've updated Windows to v. 2004. The problem still occurs. I've also substituted a perhaps more informative image for the original. Note the blank area at the top and the title bar, which is nonfunctional.

    • Click on "List all Modes"
    • Select the preferred display mode. Something with at least 60Hz.
