Unable to release grab from guest

[DrissiReda]

I managed to install everything, it works. But when I want to release grab through Ctrl+Alt+G it doesn't release it. And my keyboard and mouse keep grabbed by the VM so the host cannot take back control. I am then forced to shutdown the VM from inside it.

This is a very weird bug as I've used QEMU before and even ra1nstorm, and this only happens on a single machine.

Bonus problem (not sure you can do anything about it): I lose wifi/bluetooth/ethernet when the PCI passthrough is activated, from both host and guest. I am then unable to use internet, unless it is through usb (e.g. modem or phone hotspot). This probably happens because my usb controller and my other controllers are in the same group, so QEMU is unable to isolate the USB controller alone.
