Description
Hi,
I tried using ComposeFilter to combine several previews into one mainviewport via ComposeFilter, but this seems to be breaking in 3.1.0-beta.
My test was:
- 1 preview with red background rendering into texture
- 1 mainview, BlackNoAlpha background with ComposeFilter, texture from preview
- Red screen is expected.
This works in 3.0.10, but not in 3.1.0-beta

Research direction
Reproduce the described preview-to-mainview setup with ComposeFilter and compare its behavior between 3.0.10 and 3.1.0-beta1. Start at the FPP and ComposeFilter entry points, using the linked discussion for context. Done means the red preview renders correctly into the main view in the affected version.
