Comment # 1 on bug 1220524 from Bit Juggler

Considering the fact that

host: MS Windows 10 (“pure” Oracle VirtualBox 7.0.14)
guest: Kubuntu 23.10 (“pure” Oracle VirtualBox GuestAdditions 7.0.14)

works fine I think there is some strong evidence that openSUSE Tumbleweed (as
guest) might be the cause of the problem.

I have no idea how to debug this any further.

But if I can be of any assistance ...
