If the problem relates to workspace switching in 18.04 then there's also a good chance that this is bug 1812527.
Sorry I am unable to reproduce any such problems here, yet. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1817682 Title: Ubuntu 18.04 interface freeze - during video call or screen sharing (using Slack or Zoom) Status in gnome-shell package in Ubuntu: Incomplete Bug description: I'm using Ubuntu 18.04 (bionic) GNOME 3.28.2 .15.0-45-generic Since some updates in the last 2 weeks the interface started to freeze for 15-20 seconds and then reloads (like a crash of the UI, then it got killed by the OS, and then restarted). The computer is unusable for 15-20 seconds then it works as nothing happened (I got proper sound and I believe everything is working - I just don't see it and I can not interact). I updated again and again (with the hope it's something terrible that affected a lot of users and is already fixed, but looks it's not). I started observing the problem more closely: The logs app that comes with Ubuntu shows this error (under System section) at similar times the interface crashes: gnome-shell[22505]: segfault at 28 ip 00007f9a80434fe0 sp 00007ffd7fb8b058 error 4 in libmutter-2.so.0.0.0[7f9a803b1000+157000] gnome-shell[3366]: segfault at 28 ip 00007ffa74598fe0 sp 00007ffc912713c8 error 4 in libmutter-2.so.0.0.0[7ffa74515000+157000] The problem appears in most cases when I'm on a video call using Slack or Zoom, so probably be related to that (not sure is it limited to that actually - may be it happened even when I was not on a call). I heavily use multiple desktops and switch between them very often (on a single TFT display). I'll be glad if anyone has an idea how to resolve this or report it (without reinstalling, which actually may be faster and easier).
