BIOS interface looks strange when using QXL in QEMU/KVM

[kuwii]

Describe the bug

When set video device to QXL, the BIOS interface looks strange.

This bring troubles in some cases like unlocking Windows BitLocker because I can hardly see the input.

Steps To Reproduce

Steps to reproduce the behavior:

1. Related configurations:

   virtualisation.libvirtd.enable = true;
   virtualisation.libvirtd.qemu.swtpm.enable = true;
   virtualisation.libvirtd.qemu.ovmf.enable = true;
   virtualisation.libvirtd.qemu.ovmf.packages = [ pkgs.OVMFFull.fd ];
   services.spice-vdagentd.enable = true;
   
   environment.systemPackages = with pkgs; [
     virt-manager virt-viewer
     spice spice-gtk spice-protocol
     win-virtio win-spice
   ];

2. Create a virtual machine in virt-manager, with
   • Chipset: Q35
   • Video device: QXL
3. Power on the virtual machine.

Expected behavior

Should normally show the interface.

Screenshots

Shown in the description.

Additional context

I hit this issue several months ago. And I can repro this on both of my 2 NixOS devices.

They are all using Nvidia driver. Not sure if it is related.

"tianocore" is from the uefi bios in OVMF ... is this different?
