Reopening to continue the discussion.

@bigdiff There are reports that spice-app works with Qemu 7.0 on Arch Linux
@PloniAlmoni As you are seeing this on Gentoo, maybe more research is required. Perhaps to determine if this is a bug/regression in Qemu itself?

It is possible I could change the default renderer in Quickemu to --display gtk, but that needs testing because I found the GTK render to have some other issues which prevented it from working reliably for everyone.

EDIT: Temporary workaround: edit the vmname.sh file in the vmname/ directory. Remove -device virtio-vga-gl,xres=1664,yres=936 and also remove ,gl=on from the statement immediately afterward. The vm will launch, though it will not have GL acceleration.

Thanks but I prefer to wait for a real fix. OpenGL acceleration with virgl (dev build) is pretty good on my system and I’m not in a hurry tbh

Out of interest does this work:
quickemu --vm myvm.conf --display gtk

Yes it does, also running quickemu v4.0

Can those of you with system running Qemu 7.0 confirm if either of the following work for you:
quickemu --vm myvm.conf --display spice
quickemu --vm myvm.conf --display spice-app

Both work here on arch, qemu 7.0 and quickemu 4.0

When testing can we also post the quickemu version:

quickemu --version

4.0

For me, quickemu --vm myvm.conf --display spice works, quickemu --vm myvm.conf --display spice-app errors out with ERROR! Requested output 'spice-app' is not recognised.

Can those of you with system running Qemu 7.0 confirm if either of the following work for you:
quickemu --vm myvm.conf --display spice
quickemu --vm myvm.conf --display spice-app

quickemu --vm myvm.conf --display spice

Is working

quickemu --vm myvm.conf --display spice

Is not working
