Additional Comments

Cosmic told me this is a decomp error; so basically after loading a handful of stages, the game will start to flicker certain sprites (at random) and certain shades of color (at random) for 1 frame or so.

It will continue to flicker on that fade in/fade out until you exit and re-open the decomp.

x64 1.3.2 release (no fork or anything like that)
Full game run with no Dev Menu usage whatsoever

Happened in SS3 whenever lightning struck

Then used the Dev Menu to open the Presentation --> Stage Select screen
Loaded WW2, where it very obviously happened on fade out (despite not happening in the full game run):

Close decomp, re-open, no flickering on either stage.

It's like the Decomp is retaining things in memory that it's not dumping on F5 but will dump when the player closes the game.
I'm a noob, so whatever you guys can figure out I appreciate.
