[UPDATED FILE DOWNLOAD] Smoothie Smash (Club Penguin) - Player color turns white on some frames

[ChrisCPI]

Describe the bug

The color of the penguin that the player controls (the penguin that is bouncing up and down) will turn white on certain frames. I've noticed that it most noticeably happens when the penguin is either twirling in the air (by pressing the up arrow key when jumping off of fruit) or falling in mid-air, both for around half a second.

Expected behavior

The penguin is supposed to stay black (or whatever color its tinted to) the entire time.

Below are two videos for comparison between Ruffle and Flash Player running the same file (apologies, I'm not sure how to embed videos properly).

It's likely that this is another case of "BMD.draw doesn't preserve filters".

The same bug occurs in other AS3 mini games.

Does #21672 fix this? Only suggesting this based off of McSweeny’s comment, but I kinda doubt it.

It doesn't, unfortunately

The MWE consists of two MCs: character 4 and character 5. Char 5 (sprite, 12 frames) contains char 4 (sprite, 24 frames). Char 4's frames change shape's matrix, whereas char 5's frames do nothing. The reset button sets char 4's color transform.

It looks like the fact that char 5 contains char 4 breaks resets color transforms at some frames (possibly when looping char 5?). This does not happen when there's no char 5.

breaks resets color transforms at some frames

It does indeed seem to happen when the outer MC (char 5) loops. In addition, having it stopped and then going to a previous frame will break the color transform.
