[libvirt] Libvirt 5.9.0 Lags

Hello all, I am using Arch Linux 5.3.13-arch1-1 and libvirt 5.9.0. After I made a linux update (sudo pacman -Syu), I got the new, libvirt version mentioned above. But soon after I realized, while programming in eclipse, that copy paste does not work anymore. After couple of tries, when I try to copy some lines of code, it freezes for a short time, and looses the copied text in the clipboard. I converted the VM's into vdi and continuing to work with virtual box. There, on the same laptop and the same VM, I don't have that issue! Is this a known issue? I really need a fix urgently, since I ve got other VMs which are optimized for KVM. I ve also post this issue to stackoverflow: https://stackoverflow.com/questions/59155986/lags-in-libvirt-5-9-0 Many Thanks, Dincer
