Re: KDE Desktop Cube Doesn't Work

Solution:

    "sudo pacman downgrade"
    "sudo pacman downgrade qt6-quick3d"

Select the most recently installed version marked with a “-” and reinstall it.

Long live FREE SOFTWARE, long live LINUX!

Edit: This issue was caused by me updating KWin without updating qt6-quick3d. In other words, I had performed a partial update, and I’ve now seen how critical that can be for Arch Linux. Once I ran a full system update that included both, the issue was resolved.
