Fix Version/s: 0.4.15
0.4.9-RC-25-g98e87bc gcc dbg
Peazip shows icons in buttons in the menu bar vertically flipped.
I think this did not happen in 0.4.8rls.
So I think this is a regression, that we should regress-test.
If we could fix this on its own, we could also fix
CORE-14649 completely (where I noticed the flipping as a left-over issue as well).
We should regress-test this before 0.4.9rls. Maybe we can still fix it.
