Terminal output (with notes)

When you attempt to minimize FL Studio, instead of minimizing, a small label
separate from the main window appears instead. If the main FL Studio window is
maximized when you attempt to minimize it, it doesn't change size, but if it's
not maximized the window is resized to a small square.

The contents of the main window after attempting to minimize is an after image
of what was rendered before minimizing, apart from a small section of the top
left corner of the application (which is just a after image of the minimize
button). If you change the size of the window in this state it shows a
trailing/ghost effect (think IE6 effect) of whatever is behind the window, e.g.
the desktop background.

I set the severity to minor because it makes minimizing the window
inconvenient, however there is a simple workaround: either use the keyboard
shortcut for minimizing on the small label window, or click on the taskbar
button/dock icon for FL Studio several times as necessary. FL Studio then
properly minimizes.

I've tested on elementary OS (Pantheon) and Fedora (GNOME 3) with Wine 3.4 and
it happens on both.

On Windows, when minimizing under normal usage you don't see this label,
however if you rapidly minimize and restore FL Studio you can very briefly see
it. With this in mind it might be that the label itself is normal behavior but
it's supposed to immediately disappear or minimize.

I attached the terminal log (with some notes). I'll attach some footage soon.
