Cycles won't render from Render Region I press Ctrl+B and create a region for Cycles to render in Blender 2.92. The border is visible in the viewport and it all looks set to go. But every time I hit F12 to start the render, Cycles ignores the region and starts rendering as it would from the full camera view. I tried everything I could think of, including disabling the camera, but nothing seems to fix it. What could I be doing wrong? Could someone help me please?
This is how I've set Cycles up for this scene.

And this is how I've set up the Output Properties. As you can see Render Region is ticked.
From Blender Manual: https://docs.blender.org/manual/en/2.92/editors/3dview/navigate/regions.html#render-region
Render Border is rendering part of your scene when you're in rendered shading mode. If you want a rendered result you'll have to set up a camera for that view.
