Issue description

I've video recorded the issue here: https://www.youtube.com/watch?v=RHE1Y0t5pw8
(It had to be recorded with my phone because using screen recording programs seems to stop the bug)

Issue:
About 5% of the time launching the game (via the engine) animated tileset tiles will flicker black.

So far I've learned:

• Using a screen recording program or restarting the game stops the bug
• The bug is not dependent on player input
• The bug only occurs with animated tileset tiles
• The tileset tiles in question are only animated (there are no other special settings or data on them)
• The flicker does not coincide with any specific frame of the animation
• The bug also does not seem to be linked to any of my other game systems' timings (the project is still very small)

Steps to reproduce

I don't know if this will reproduce the issue for other people, as it's not 100% and is really quite unpredictable, but I:

1 created and imported a tileset sheet with animation frames
2 set up the tileset to animate using the frames in the spritesheet
3 placed the animated tiles on the map
4 load the game and watch the tiles
5 repeat step 4

^ I've attached there the tile spritesheet I am using, since it won't let me upload the project.
Note that only the tiles with contents are included in the animation (the empty ones on the top right are not)

The sand tiles which also flicker black on the same timing, are also animated with the same number of frames, but on a different spritesheet on the same tilemap

maybe related/same

#82286 maybe related/same

Might be! I have a a purple flat image behind these tiles, and the flicker happens on random seeming frames, but maybe it's the same culprit. Happy someone's looking into it :)

@InfiniteDistraction Please test if you can reproduce it in 4.2.dev6 version which includes the fix for #82286 (be sure to backup your project when trying different version).

If it's already fixed in there then (if you'd want) you could also test 4.2.dev5 for confirming that's indeed a duplicate of #82286 (which would be the case if the bug is present in 4.2.dev5 but not in 4.2.dev6).
