Strange graphical issue. No acceleration? Under iMac sonoma (intel)

Hello. I have strange polygons in view. It apear after adding some parts to view.
Beside app is very laggy. More object = more laggy.

When I rotate object it follows object.


after restarting app it deseapear.

Thank You.

Based on Apple’s website your computer is not supported by Sonoma.

Are you trying to say that only for that application I nead other hardware? Plasticity works. Sketchup works. Modo works.

But it is running Ventrura and Sonoma. On older imac with GTX6xx, shapr works perfectly on sonoma and Ventura.

We don’t support hackintosh.
