Virtual Box black window

Noticing when I open virtual box it is only a black window. Not sure when it started happening. There is the window border and decorations but nothing inside the window, just black nothing rendered. If I right click where a machine would be I can click start to get into a VM and that window will render but not properly, I have to make it full screen. I’m not sure if this is just me or there is an issue with it. I checked the bug list but diidn’t see anything that stood out. Its like this on two different machines for me. Just curious if anyone else has seen this. I’ve just tested both X11 and Wayland and its the same on both machines.

Version of VBox?

Previous version it worked fine?

What OS - Leap - Slowroll - Tumbleweed.

What guest - Windows, Leap, Ubuntu, XP?

What does “zypper se -si virtualbox” show

What video driver is selected for the Guest

Have you uninstalled all VirtualBox versions and reinstalled the latest. Funny things happen when old kernel drivers and new kernel drivers load at the same time.

sudo zypper rm virtualbo*
reboot Yes that is an asterick in the above line
sudo zypper in virtualbox
reboot

now see if it works

I figured it out. Kvantum theme was the issue.

It says “Tumbleweed” in the title bar above?!?

Personally I do not understand why this is in “Applications” instead of in “Virtualization”.

Just for nitpicking. When one wants that * to be interpreted by zypper, one should protect it from being interpreted by the shell through escaping. E.g.

zypper rm 'virtualbo*'

or

zypper rm virtualbo\*

Thank you @deebido , I had the same issue!!
