SUMMARY
Virtualbox on Wayland win 11 VM.  When you try to use either the View/Full Screen Mode (right control F), View Seamless Mode (right Control L) , or View/Scaled Mode (right control C) Fedoras UI either Freezes, crash or the Virtualbox screen disappears.   This behavior does not happen on X11 where it works as expected.  I have the same issue on an Acer laptop with Mesa Intel drivers and my Dell Workstation with open-source AMD drivers.  This seems to be a Wayland issue.   I have all latest drivers installed.


STEPS TO REPRODUCE
1. Create a Win 11 on Virtualbox
2. Hit View/Full Screen Mode (right control F), View Seamless Mode (right Control L) , or View/Scaled Mode (right control C) 

OBSERVED RESULT
Unexpected behavior is seeing where Fedora just crashes, and you have to hard boot the machine or sometimes the Virtualbox screen completes disappears (it is not he Seamless Mode)

EXPECTED RESULT
Virtualbox enters into its proper screen states that you requested, and Fedora does not crashes.

ADDITIONAL INFORMATION
This is really important for us since we use WIN 11 VM to connect to the office.  The VPN does not support Linux.  It is very high priority due to decision by Fedora to not support X11 on next version of Fedora 40.  This will stop us from updating to any further version until this issue is resolved or Fedora changes mind and allow us to keep switching back to x11.
