Ah! Thank you.

So far things look no different with either one or both of these set. I'll
test more as time permits, and see if I can find any better test-cases, and
will also look into those bug reports mentioned here.
In the initial report, being in a bit of a rush, I forgot to actually describe
the issues here (instead of just linking), so I'll do that here at least a bit.
KWin: This one show up so that I'm unable to move any window past the top and
left borders of the screen(s), and the also behave in a weird way when trying
to push them past them, and then resizing them, making the adjustment 'jump' a
lot at once. This also makes the LXQt panel behave in strange ways when set to
these locations; it will not animate automatic hiding of it, and it acts as if
it's always visible, even when hidden (so if clicking something below it, while
hiding, the click still goes onto the panel even if it's supposed to be
hiding).
Wine: There are issues with stack alignment leading to application crashes
triggered after a change made to the Wine code [1].
