I hope whoever is reading this is doing well. The issue is that I am getting screen stuttering/lagging on some distributions when I run them as VMs using virt-manager. The issue occurs with distros like Fedora, Kali, and Manjaro. However, the VMs of Ubuntu and ParrotOS (I think it is based on Ubuntu) work fine and smoothly. The information regarding this topic is either scarce or not addressing the issue that I have.
I have a hunch that it has something to do with Spice. I have installed spice-vdagent on the guests but it hasn't helped. May be I am doing it wrong. But I found this in just one post on a debian forum linked below.

Furthermore, I have also found that it can be due to missing virtio drivers on the guest machines. But I don't know how to use this information as it is unclear for me. The screen stutter increases with increasing the size of videos and is reduced when the size of the video is reduced, for example, full screen video stutters more than when the size of the video is reduced.
What can be wrong and what do I do about it? Thank you
