--- Comment #13 from Nate Graham <nate at kde.org> ---
The TL;DR here is that the default VirtualBox graphics driver (VBSVGA) driver
is broken-ish, and has been for years, and a necessary change in KWin now
requires that it not be broken in that way. Ultimately VirtualBox just needs to
fix their driver or make a different one used by default.

Until one of those things happen, users of VirtualBox will need to alter their
machine settings in one of the following ways:
- Enable 3D acceleration if there are no security concerns
- Switch to the graphics driver to VBoxSVGA if there are security concerns
