## SPICE display causes freezes
Windows 10 and Windows 11 guests may freeze approximately 20 seconds after boot when using `--display spice`. The freeze typically occurs when interacting with the VM, such as opening files or a web browser.
**Workaround**: Use the default SDL display instead of SPICE:
```shell
# Instead of this (causes freezes):
quickemu --vm windows-11.conf --display spice
# Use this:
quickemu --vm windows-11.conf
```
**Trade-off**: Window resizing and SPICE-specific features (clipboard sharing, USB redirection via SPICE) will not be available with SDL display.
This appears to be an upstream SPICE/QEMU limitation rather than a quickemu bug. See [issue #1670](https://github.com/quickemu-project/quickemu/issues/1670) for details.
