Public bug reported:
I'm using join-display with an built-in laptop HiDPI screen and an
external 1920x1080 screens. I set fractional scaling 200% on HiDPI one
and 100% on 1920x1080 one.
The emacs window on 1920x1080 screen displays clearly, but blurs on the
HiDPI one.
If I switched to non-fractional scaling(still 200%, 100%), then it does
not blur, but only the top-left area of my HiDPI screen displays while
the remaining area is black.
