On native Flash Player 32, the screen should not become fully white.

See the doSnow function on frame 50 => DoAction[5]. This is drawing a texture to a bitmap using DisplacementMapFilter, then overlaying the screen with that bitmap. Since the bitmap is in the "mrs" movieclip, you can toggle its visibility in the Ruffle desktop app's debug tools to turn the screen back to normal.
