Hi Volker if I remember correctly, ray casting will apply to all enabled surfaces. It’ll ignore off screen surfaces and surfaces where the cursor is outside the render area. I think it also ignores surfaces when an orthographic camera is used.
So in your case sounds like you should only get a single hit in the main area, and two when testing in the render areas. 5.13 is introducing a QNoPicking frame graph node to explicitly disable picking and ray casting on portions of the frame graph. If you continue having issues with this, please create a JIRA ticket, ideally with a small example.
