Unable to view movies without moving mouse constantly

First time attempting to watch a purchased and downloaded movie with macOS 10.14.5 and iTunes 12.9.5.5. Never had a problem prior to this with previous versions.

Now, no matter which movie I try to watch, if I don't constantly keep the Magic Mouse 2 moving around, there's sound, but only a black screen. Move the mouse, video instantly appears. Stop moving the mouse, black screen.

Any ideas? Thanks!

Edit: Seems it only happens in Full Screen view. When it goes to hide the on-screen controls, it also hides the picture. Works fine in windowed-mode. Annoying, to say the least!

Mac mini, macOS 10.14

I have the same problem, on a new Mac mini. Movies will play full screen if I put the cursor at the top (so the menu bar is visible) but not if it's anywhere else. They play fine while the controls are visible and then go blank (black screen) when the controls hide. This is in QuickTime and BBC iPlayer Downloads, but not in VLC.

Have rebooted, deleted QT preferences, changed display settings to scaled at different resolutions, etc.

If I access the machine remotely via Share Screen it doesn't happen – it plays 'full screen' fine in the window on the remote computer.

This seems to be the same as reported on another thread:

Anyone else getting this?
