Opensuse leap 15.3 guest screen issue

[hadan]

Hello,

I use workstation pro 16 on windows 10 host and have created opensuse leap 15.3 guest.

The other day, I played around with resolution/font setting in the kde display and font settings , because font looks smaller in the guest for the default 1920x1080.

Anyway, now  after I started up my opensuse, the screen is broken (screen shot provided).

Even after I use boot safe mode from opensuse iso. The command line screen is cut and can't get around to do setting,etc.

How to get back to default resolution?

thank you

Hmm, even when I tried to reinstall vm guest, the small screen problem still exist when booting the opensuse iso. Now I am suspicious this due to windows host update, because now I remember after I had played around with opensuse guest display resolution, I did some windows host update that install bunch of things. Anyone have a clue?
