Resolution Note:
Overlay cameras do not write to target textures, that only applies to base cameras, the overlay cameras then write on top of the base camera target texture, so rendering the UI to the overlay camera and expecting to access the frame results by referencing the overlay camera target texture is wrong usage. This used to work before 21.3 because it was a bug/undefined behaviour, which was fixed in that version.
The correct way to make this scene work as intended is to:
- change the UI camera to base camera
- change the priority to 1 so it is rendered after the base camera
the Capture script should now work correctly
