boxes fedora 40 beta login screen

SUMMARY

if you install kde workstation(39/40) in a vm(boxes in this case), when you first boot the login screen doesnt take up the full screen. if you login the screen goes to the correct size. if you restart from logged in state, you get the correct size upon being presented the login screen again.


STEPS TO REPRODUCE
1. install fedora 39 or 40 beta into vm. i used boxes.
2. restart.
3. wait for first boot login screen.

OBSERVED RESULT
login screen is a fraction of the correct size.

EXPECTED RESULT
login screen to be the size of the boxes window.
