Weird Wayland window pops up repeatedly on virtualization?

What I’m guessing is a clipboard client for Wayland support named “vboxwl” keeps popping up every time I interact with the host machine. It auto focuses on the window and minimizes without actually displaying anything inside the window, which is very annoying and distracting. No idea how to disable it and the docs don’t tell me anything about it.

I am using Fedora KDE Plasma Desktop 43 with VirtualBox 7.2.4.

Thanks for your help,
Jeroen.
