Issue type

UI bug (incorrect info or interface appearance)

Bug description

The screen goes blank after hovering over a button on the top menu, seeing info dialogue, then moving mouse to remove info dialogue.

Steps to reproduce

1. Create a score
2. Hover mouse over item in top menu, like "Voice 2". The info dialogue should appear
3. Move mouse again and info dialogue disappears, as well as the entire score
4. Score does not reappear until doing something like zoom in.

Also happens in palettes, anything with that little dialogue box with pointer.

I'm getting this issue all over the place - e.g. while saving

Looks to have been introduced with this commit (FYI @cbjeukendrup @Eism)

There are various "flashing" instances of this.

Clicking out of mixer settings menu then clicking on score, selecting and deselecting boxes

Please let me know if I need to log this separately

According to @zacjansheski this still occurs in master, so we're keeping this open for now. @cbjeukendrup FYI.
