RT Activeshade is not locking to the viewport to render ?? Very frustrating !

This never used to be the case.

And it means I can’t render the camera viewport whilst playing in other viewports to move lights etc ??

RT-Activeshade Cuda is what I am using (and the padlock is active and chosen for the Camera Viewport).

Okay, it happens sometimes, and sometimes not…

(maybe I have to wait for RT to ‘settle’ in activeshade first…)
