Application Render Opacity/Transparency on Secondary Monitor

[rafe2486]

Issue type

UI bug (incorrect info or interface appearance)

Description with steps to reproduce

When running MuseScore on a second external monitor, the UI becomes transparent after being dragged to that monitor. Dragging it back to the original monitor causes the transparency/opacity to stick until user action (click, mouse over, window state update).

Steps:
Launch MuseScore. Drag application to a second or external monitor.

Workaround: Setting desktop background to solid black makes the transparent window usable. Those who have a dark solid background and no other open windows behind the application on the transparent screen might not notice this issue.
