[SOLVED] Orthophoto bounding box not updated

Since the update 2935 (Promo), the corresponding bounding box of an orthophoto is not updated anymore, when selecting a different one. Only with a step in between (like clicking on the model and then to another orthophoto) will show the correct bounding box.

BTW, what are the red arrows for? Just for the viewing direction?

With a freshly opened project, it works fine.
Also when I change the component once.
Or maybe it works once for each component - I only have projects with max two components and orthos at the moment.
After that, it shows this error…
