Sorry if I wasn't clear  - it's the *host* window size that is messed up for me.

Not sure.

One Pi has a 1920 at 180 screen and the initial window is notably smaller than what it was when I saved the image, the other has a 1920 at 1440 screen and the initial window size is what I set. That size is not larger than the 1920 at 1080 screen, by the way. To the best of my recollection this is new (mis)behaviour.

Has anyone changed this code recently? Or is this a side effect of recent scale factor stuff? I can't spot any suspicious code in the image right now.
