Screenshot how it should look like

First, enable virtual desktop in winecfg for easier testing.
Then run the game, click Start, then Start again to enter the Level Select
screen.
Here you can press save. But when clicking that button the game seems to freeze
without the save dialog showing.
If you click where a button should be now, the save dialog gets shown.
When you click a save slot button, the same thing happens.
You need to click again where a button should be to make it visible.

See attached screenshot.
