I installed Fedora-KDE-Live-x86_64-34-20210212 in a qemu VM.

I am unable to get the guest to auto-resize when I expand the console window.  I am also unable to select an alternate display size with system-settings or xrandr (using plasma on X11).  If I select Virtio as the video card I can use system-settings to select a reasonable size but still unable to get auto-resize to work.

With the Workstation version of F34 auto-resize works as desired.

So, I installed gdm on the F34 spin and now auto-resize works.  It therefore seems a problem with sddm.  I didn't locate a BZ to address this.  Is this a known issue being worked?
