Update: After some additional testing, It would appear that only the cube desktop switching animation causes a crash. Fade and slide work fine. Could you please install kwin debug packages and submit a new backtrace? Hello, there! Which packages would that be? I've installed kwin-dev but the stack trace appears to be nearly identical. Sorry, I have no idea what packages you have to install on Ubuntu or Debian. I suggest to seek for help on your distro's forum.

Committed on 07/05/2019 at 12:13. Pushed by vladz into branch 'master'. [effects/cubeslide] Cancel active animation when number of desktops has changed Summary: If a virtual desktop is removed, then desktopChanged will be followed by numberDesktopsChanged signal. In which case, we have to cancel the active animation because front_desktop might be no longer valid when it's time to perform compositing.
