Bug 480143

SUMMARY
All window borders/titlebars are missing. I am unable to move around applications, open/close them, and all windows spawn in the top left.

Display and Monitor -> Compositor in settings shows no issues. The previously posted hotkey to "enable compositing" does nothing.

This issue does NOT occur on Ubuntu Jammy (5.24.7).

This issue does occur on KDE Backports Extra PPA on Ubuntu Jammy (5.27.10) https://launchpad.net/~kubuntu-ppa/+archive/ubuntu/backports-extra
