Still occuring and pretty sure it is a mouse related issue as I tested with a keyboard with a integrated trackpad mouse. No hiccups nor losing 3D model focus using this device. Going back to wireless Razer mouse, stutters occur and mouse moves does not reflect correct rotation, 3D model slowly going down while I move horizontally.
Also noticed that changing mouse polling rate in Razer app affects 3d model rotation render in a weird way... The lower the smoother. 125Hz polling rate is smooth, everything above make case models stutter
Invocking grandmaster @faeran , fingers crossed
