VM preview screeshots have a tendency to corrupt themselves

[UrkiMimi]

Describe the issue
VM preview screenshots end up corrupting themselves while I'm using the program. About 3/5 VMs I have on my system have corrupted previews. I'm not sure if this is an issue with QEMU directly since it doesn't come out corrupted when the screenshot is taken initially.

Configuration

• UTM Version: 4.4.5 Stable
• macOS Version: 14.2.1
• Mac Chip (Intel, M1, ...): M1 arm64

I believe this is the same root cause as #4009 which should be fixed in the next build.
