Sometimes there is a noticeable few second delay when changing screens.

This happens because game waits for keyboard and mouse release events when changing view.

Issue is reproducible on Windows 10 by:

Clicking a button etc., which initiates view transition, using mouse and then moving mouse away from the screen before releasing mouse button. Game releases the transition only when moving mouse back to on top of the game window.
