Description

SceneCaptureComponent2D Anti-Aliasing does NOT work unless Post-Processing hidden show flag is toggled OFF and back ON again. This state persists only during Editor time. Upon restarting the Editor and opening the project again, the state of the Post-Processing checkbox has to be cycled OFF and ON again to make anti-aliasing work in SceneCaptureComponent2D component again.

Found in 4.22 CL# 7053642, 4.23 CL# 8243292, 4.24 CL# 8360499

Steps to Reproduce
  1. Open the attached Project.
  2. Locate "RT" render target in content browser, and open it.
  3. Set Zoom value on the bottom right portion of the render target viewer window so that you can view render target output at 1:1 resolution.
  4. Open the LevelSequence in content browser.
  5. Play through the Sequence with the render target open

Result:
SceneCaptureComponent2D Anti-Aliasing does NOT work unless Post-Processing hidden show flag is toggled OFF and back ON again.

Expected:
SceneCaptureComponent2D anti-aliasing works always and reliably, as long as Post-Processing is enabled.
