Full screen causes Kodi to vanish

Log: https://paste.ubuntu.com/24640455

When I toggle the backslash button to make Kodi fullscreen, Kodi disappears. If a video is playing, the audio remains. Kodi also crashes from time to time in an unpredictable manner.

This behavior started from my first install of Kodi three years ago. I figured it was a bug which would be repaired. Well, now I’m on 17.2 and the problem has just gotten worse and more frequent.

Today, after using the Kodi Backup addon, I uninstalled Kodi with Revo Pro, then did a clean install, restoring with Backup. Towards the end of the restore, Kodi crashed. I restarted it and ran restore again.

The problem remains (among others for other threads).

Any ideas? Thanks!
