pixels in the work screen sketchup pro 2022

[ILA_RIA]

Good morning, I'm new here on the forum and I need help. I tried to look in the other arguments already present but I couldn't find answer to my problem. I've been using sketchups for a couple of years and I've never had any trouble. the pc on which it is installed is always the same but from a few days when I start creating my models I appear to be pixels as you see from the photo I have attached. I have not touched settings (at least not intentionally) and I do not understand why they see. Unfortunately then these pixels I also translate them into the program I use for making that is 4d cinema. it really becomes complex to work on why they grow more and more depending on how rough the model.
I hope you can help me solve this because I don't really know what to do!

Thank you very much
Ilaria

It's really weird. Perhaps the model file has been ruined, that is the one from which you start to create your own files.... to understand what only presents a two-dimensional human figure. If so, you would just take a previous file (when everything still worked), delete all objects and use it as a model.
