Ok. I go to terminal and put a command sudo apt update && sudo apt upgrade then i logout and back and Zorin appearance start working.
Propably this can be issue because using a pendrive ?
I don't wanna be rude to put something what not working but this is distributions for beginners users.
I little learning with linux "things" but certainly i am dissapoint after 5 minutes i have many problems with some errors.
On webside it wrote "working out from the box".
I remember on my old PC I have some issue with my graphic card what we found a solution here with all your help people and many another problems.
That why i never used ubuntu only most two what you know was Zorin and Mint.
Last time was Fedora and now Mx Linux before new version Zorin coming out.
The problems are my hardware is not compatibility with version Zorin 16.3
