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).

I have have accidentally discovered the root cause when attempting to replace the currently running kwin_x11 instance KWIN_OPENGL_INTERFACE=glx kwin_x11 --replace kwin_x11: symbol lookup error: /lib/aarch64-linux-gnu/libkwin.so.5: undefined symbol: drmModeGetConnectorTypeName This appears to be a result of https://invent.kde.org/plasma/kwin/-/commit/f881bdf51b55b0ace76e9919b812ba87c8a8f040 According to the package properties this is only for drm output on wayland. Yet I am using x11, so why is this symbol required?
This is an issue with the build/installation.
