Bug ID: 58433
           Summary: entering sub-menus makes entire menu vanish behind
                    main window in FL Studio (virtual desktop mode)
           Product: Wine
           Version: 10.11
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: win32u
          Assignee: wine-bugs@winehq.org
          Reporter: cyrus.valkonen@gmail.com
      Distribution: ---
When any menu is opened, such as "File ...", and then a nested sub-menu with
more menu options such as "New from template ..." is hovered (not clicked) with
the mouse to open it, the entire menu with sub-menu is suddenly rendered behind
the main window (z-index issue?).
Consequently the user can no longer open files and can no longer access a lot
of important menus in a lot of the DAWs functions, such as music sheet editor,
pattern editor, etc.
In Wine 8.1 this bug does not occur, and must have been introduced somewhen
after (my guess is version 9).
Please note that this issue does NOT relate to X11, because it happens with
"Emulate a virtual desktop" checked.
I tried many things to work around it, including monkey-patching Wine 10.11
source, but everything is unsuccessful. Please note due to issues with VSTs, FL
Studio needs very specific combos of NOT using DXVK, and not overriding
d3dcompiler_47 or dxgi with winetricks. But even if used it makes no
difference. There are NO OPTIONS in FL Studio that prevent this bug (such as
unchecking ultrasmooth mode or disabling window animations). Only regressing to
8.1 fixes the bug.
In the logs you will see two "TQuickPopupMenuWindow" being opened. The first is
the menu, the second is the sub-menu.
Many versions of FL Studio and Wine are affected by this. At least since FL 20
and Wine 9.
Sadly because of changes in Juce (used by many VSTs), a lot of new and critical
VST plugins now do require a very recent Wine version. Thus falling back to
Wine 8.1 is no longer viable.
