Should Scratch 3 collisions be deterministic?

[griffpatch]

Expected Behavior

Playback of gameplay movements recorded into a list should result in the same game play video each time independent of screen resolution.

Actual Behavior

At full screen / project view sizes the game play changes, I suspect due to differing collision regions / rasterized silhouettes? This may well be something that is the desired behavior based on Scratch 2 compatibility? But it would be nice for your project to run the same no matter fullscreen or windowed. Would be nice to know if this is expected :) thanks.

Steps to Reproduce

1. Open this project but do not go fullscreen - https://scratch.mit.edu/projects/292297781
2. Run project and 'watch' level 2 - Level will complete
3. Now go fullscreen and do the same again - This time the player dies hitting one of the enemies.
4. Go back to project player size and repeat - Player continues to die.
5. Reload the project and now step 2 works once more...

The game was designed to be deterministic. I can't guarantee this is the case at present as I haven't done thorough tests of how the broadcasts might get out of sync under heavy load, but it does appear to play back consistently at a given resolution. This leads me to my conclusions in 'actual behavior'.

This issue seems to be in scratch-renderer.

Seems like there is already an issue there too: scratchfoundation/scratch-render#656
