Here’s an example. I open Preferences in Nautilus file manager, the preferences window opens almost in slow motion.
I can’t really test videos at the moment cause of Qube <qube> has failed to start: 'UnknownDevice' object has no attribute 'libvirt_name'
Sounds like a graphics issue. My CPU has integrated graphics, I can’t tell whether the qube is running with my integrated graphics or my dedicated graphics. Is there a way of checking? I tried connecting my GPU to my fedora template VM in Devices, ran the VM and my pc crashed.
