Octane Viewport greyed out after render

[Longbongosolo]

Hi, I'm having an issue where whilst rendering the Octane Viewport is normal, but as the render completes the image is replaced with grey and the toolbar is mostly greyed out. This happens with fresh scenes.

Using Blender 5.1.2, Octane Add-on 31.8.0 on Win.

During render...

When render finishes...

After a render, the Octane Viewport needs to be closed and reopened.

Also, please keep in mind that the Octane Viewport in Blender is mainly intended for debugging purposes, and it should not be kept open while launching final renders.

For regular work, you should use the standard Blender viewport with Octane rendering instead.
