--- Comment #3 from Stuart Axon stu.axon@gmail.com --- I haven't managed to trigger it reliably - but I have worked out how to un-trigger it.
To unreliably trigger it:
Keep setting different visual styles (there are a bunch you can download on deviantart).
IE - start winecfg, set visual style then quit, then load notepad and open the file menu.
If the file menu is the height of the whole screen then then the bug has been hit.
I hit this just now switching to this theme: https://yggdrasilly.deviantart.com/art/Watercolor-Emico-Shellstyles-89232671
Anyway - to UN set this bug, just go back to winecfg and set no-theme.
Sadly, I wasn't able to reliably trigger the bug again by choosing the same theme :/
