Describe the issue
VM running with virgl acceleration in virt-manager crashes and shuts down every time there's an interaction with some KDE Widgets. Even expanding a connection in Networks widget, opening System Monitor or dragging & dropping some widgets cause VM to crash.
Regression
Yes. KDE Plasma 5.25 and 5.26 runs fine on Fedora 36 (Mesa 22.1) guests but crashes with Fedora 37 (Mesa 22.2) or any rolling distro.
