Problem with edges

[Katekbc]

Hello everyone, I have a problem after updating Corona to 12.12. The model displayed has jagged edges. Can you help? What could be the problem?

This looks like a precision issue due to wrong scale, it could be that your model is way too big, or much too small for the scene units, or it's very far away form the scene origin. Try to solve those issues and the artifacts should go away. It has nothing to do with Corona though.

I don't think that's the problem. The same model before the corona update looked normal=sharp.

I am attaching another example

I don't think that Corona has much influence on how the viewports are drawn. Anyway, i suggest you to create new simple scene and if the issue persist, you can open the ticket at Chaos support portal and attach the scene for investigation. https://support.chaos.com/hc/en-us/requests/new

Does the issue go away if you install the older version of Corona?

This looks exactly like a max scale/units issue.
Check the scale of your scene, check your system units are as expected and make sure your model isnt more than 10,000 units from the origin if reverting to a different corona version doesnt help.

This can rarely happen with normal scenes too.

Workaround is - enable viewport clipping, and move the bottom slider slightly higher (this enables clipping at some distance in front of the camera/perspective viewport).
