System, specs and windowing system? I’ve only seen that issue using wayland so maybe its that, if so, change it to x11/xorg for now until they add better wayland integration, it’ll take some time but I believe its in the works now
I can only think of ubuntu’s repos being wonky, I switched to KDE Neon for that and more reasons, I can’t think of a fix if it happens again, maybe try and refreshing the repos using sudo apt update but it may do nothing, sorry I can’t help you with more.
