Windows display blank on reboot after Windows 11 ARM preview update

Describe the issue

After an update to Windows 11 ARM Insider Previous 26200.5001 when the VM rebooted the screen was black/blank. The VM seemed to be doing stuff underneath.

I could workaround/fix this by

• Changing the display device from virtio-ramfb-gl (default, I never have changed this) to virtio-gpu-gl-pci
• Restarted VM. Display now works.
• Reinstalling UTM/Spice guest tools (this is normal to need to do after an upgrade due to the way insider previews work)
• Changing back to virtio-ramfb-gl. Display still works.

I'm not sure if this is a change on UTM (from 4.5.x) or Windows 11 ARM Insider preview nor what the differences are between the display drivers, but recording it here in case others have the same issue and need a workaround.

Feel free to close this if it's expected.

Configuration

• UTM Version: 4.5.2
• macOS Version: Sonoma 14.4.1
• Mac Chip (Intel, M1, ...): M1

Debug log
I don't think I can recreate this now - perhaps at the next Insider Preview update? :-(

For what it's worth, I didn't have the same problem after updating to 26212.5000 so not sure if this was something to do with that release; or the QEMU/UTM update. To be fair, these are Canary channel builds (necessary right now to get necessary fixes to be able to run Ruby on Win 11 arm64, and I missed my chance to switch back to dev channel at 26200)

I did another Insider Preview upgrade and did not have an issue with the display. Will close this for now as perhaps it was something quirky specific to me setup, and I am using Insider Preview builds so it's possible this is specific to that, rather than a UTM issue.

Can re-open if others have similar issues.
