screenshot showing the problem

When using the default skin (or any theme except for the Windows skin), parts
of the UI are shown in black initially.

A work-around is playing around (pressing but not releasing a button for
instance). Another work-around is switching the application to the Windows skin
through its settings. Then the issue disappears completely.

Apart from the graphical glitches, the application runs fine in Wine.
