QEMU/Virt-Manager + QXL 4k Resolution + Win 11 Guest freeze issue

Has anyone run across an issue with windows 10 and/or windows 11 guests locking up solid after a random period of time when using QXL video at high resolution and windows guest scaling? I've got two Video QXL devices for my windows 11 VM:

<video>
  <model type="qxl" ram="131072" vram="65536" vgamem="32768" heads="2" primary="yes"/>
  <address type="pci" domain="0x0000" bus="0x00" slot="0x01" function="0x0"/>
</video>

video>
  <model type="qxl" ram="131072" vram="65536" vgamem="32768" heads="2"/>
  <address type="pci" domain="0x0000" bus="0x10" slot="0x02" function="0x0"/>
</video>

They both run at 3840x2160 with 150% desktop scaling. It randomly locks up after a period of time, sometimes at the login screen. I can use VirtIO video instead but its very choppy and doing much more than web browsing pegs the CPU. I see there is a possible match for this bug over at qemu:
https://gitlab.com/qemu-project/qemu/-/ … _214460662 and a mention in the debian world: https://bugs.debian.org/cgi-bin/bugrepo … ug=1084199 but I'm not sure if anything is being done on the arch side.

I've read a few blurbs about virglrenderer but being new to Arch (I primarily use debian but used gentoo prior) I havent really looked into the AUR custom packages yet.
