If you enable Adapt to Camera View Resolution and use Render Region option at the same time the region won't be displayed correctly in the viewport.

Running latest OctaneRender™ for Blender 2021.1.3 - 25.3 [TEST] build.

Still happenning in 27.8, and now if you activate Adapt to camera View Resolution the view change a little, for exemple my 50mm camera with this option render like a 40mm.
The final render is ok, but if you place your camera with the interactive rendering you will make mistakes
