Can't view the picture during zoom in (might be flippingissue)

Flipping issue.pdf (190.8 KB)
Hi All
I am new user and learning sketchup,
I have an issue that whatever model I will create it will have issue that during zoom in the picture or model blur and can’t view it properly. (I guess its flipping issue)
I have tried all the option Field view from 0 to 120, size of the model, remove all the unnecessary items, center the model but couldn’t resolve the issue. I have attached the sample.
Appreciate for the advise.
Thanks

This is called Z-Fighting and occurs when two faces try to occupy the same place. Basically remove the face that is causing the issue, or move them apart.

Thanks,
Yes it was the issue.
