Artifacts and entities vanishing for a few frames

[LargoGitH]

Describe the bug
Artifacts show up (beacon beams change position and colors??) and entities (chests, villagers) and clouds vanish for a few frames when renderscale is enabled.
Likely just a bad mod combo (?)

To Reproduce

1. set render scale to anything other than 1
2. move around world with mobs, chests and beacons in sight
