A highly efficiency-impacting issue with UE5’s TSR refresh

As shown in the video, why do invalid clicks also trigger AA recomputation? Or when clicking the eye icon to hide/show actors, why does it probabilistically trigger AA recomputation?

This causes two particularly frustrating problems:

  1. When I need A/B comparison effects and quickly click the eye icon to hide an object, the constant AA resets create noise in the image
  2. When using F9 for quick screenshots, many captured images end up noisy due to this issue

The expected behavior should be:

  1. Toggling actor visibility via the eye icon should function identically to changing the “Visible” property (which doesn’t cause AA recalculation)
  2. Screenshots taken with F9 should maintain perfect image quality regardless of how rapidly it’s pressed, matching the clean output of standard screenshot tools
