The contents of stderr (most entries are from opening a menu and effect
nothing)

In one of the levels of Rhythm Doctor (r3b_hotfix2, but should be present in
all versions with the level), there is a point in time where the window moves
about. The window will not accept key input (which is required to play the
game) unless the mouse is hovered over it *or* you open a second window (such
as winecfg), select that, then select the game (the window will then have
"focused blue").

However, later in that level, the window completely leaves the desktop area,
and when it returns, it is still "focused blue," but does not accept input
unless the cursor is currently over it (the only fix at that point is to mash
escape and try to "catch" the window so you can pause and re-seat the focus).

There's nothing funny in the log when the window moves, nor when it leaves the
desktop (I'll attach it anyway, just in case.)

I've tested this:
With an emulated desktop with WM having decorate and control
With an emulated desktop (with wine having decorate and control)
With WM having decorate and control (without the emulated desktop)

This is wine 4.5
