If I then change the display back to 5120x1440, Mythfrontend GUI stays fine: a nice window at proper size and location. But when I start  a recording, it is squashed in the middle of the window.

If I change the screen size down to 3840x1080, then mythfrontend displays fine. I've tested using two different themes, both with qt and openGL as renderers.

I've not used Screen Aspect so you may not be able to set it corectly, if so then how dumb, but surely your screen is 32:9
