Description
I was playing with the Capturing a screenshot tutorial and I noticed that if the camera used for the screenshot has a post-effect like bloom, any UI will disappear.
You can check it on this project.
Steps to Reproduce
- Click on Play you will see two buttons;
- The left will enable and disable the bloom effect for all the cameras in scene;
- The right will create the screenshot;
- If you disable the bloom the UI will be visible;
- If you enable the bloom the UI disappears.

Research direction
Start with the Capturing a screenshot tutorial and reproduce the issue in the linked PlayCanvas project, comparing screenshots with bloom enabled and disabled. Trace the camera screenshot and post-effect rendering paths; done means the UI remains visible in screenshots when bloom is enabled.
