[4.0.0 - beta 6] Jerky movement

[SBCGames]

Version

• Phaser Version: 4.0.0 - beta 6

• Operating system: all

• Browser: all

Description

Slowly moving objects move very jerky. See sandbox example here: https://phaser.io/sandbox/kRraoccz
Probably, the position is rounded to pixels - I found this sentence in release notes for beta 5:

Limit roundPixels to only operate when objects are axis-aligned and unscaled. This prevents flicker on transforming objects.

And indeed, if I rotate or scale the object, then it moves smoothly. Also, changing engine version to 3.88.2 works.
Release notes for beta 6 say, that pixels rounding was removed from many places, but it looks it still remains active here.

I have complex animation in the game and part of the objects is moving smoothly (those, that also rotate) and part moves jerky.
