Comment 6 for bug 1724810

I have removed just guest-x11, and then it runs wayland again, but the flashes and these off-seconds are back as well. The problem seems to be directly related to wayland.

I am not familiar with wayland yet, first contact. But when installing virtualbox-guest-x11 and rebooting, the process Xwayland is absent and Xorg is present.

And it's just the guest screen, just that particular window the VM is running in.

If I don't touch mouse and keyboard, it happens only occasionally, every 5 or 10 seconds, but once I move the mouse or start a new program opening it's own window, it happens more often and in most cases immediately.

It looks like some syncing problem between virtualbox and wayland.
