MacBook Pro 14" M3 - Graphics issues while working

It’s a SketchUp issue, and you’ll find there are a lot of posts about it. A developer can reproduce the problem, and is working on a solution.

As an alternative to switching back to the classic graphics engine, you could set the antialiasing to be 0x instead of 2x or 4x. On a MacBook Pro Retina screen the lines should still look ok, and will be sharper to. And the freezing issue will stop happening.
