That is a problem with virtualbox-guest-x11 as my VirtualBox tumbleweed did that.

My fix is to zypper rm virtualbox-guest-x11 and zypper al virtualbox-guest-x11 and I had to set the video to VBoxVGA to allow resizing the video window.

my 2 cents.

All went well for a while then part the way through the installation process my graphical screen went totally blank with the cursor flashing in the top left corner.
I'm seeing this during 'zypper dup' in a VirtualBox VM since 2-3 months; another bare-metal system is fine.
I have the strong feeling that this happens any time systemd gets updated.

It leaves the bad feeling behind that the update was interrupted in the middle of something.
Since then, I start 'zypper dup' in a screen(1) session.

Have a nice day,
