When using pixel movement plugins, like DotMoveSystem or Tyruswoo’s AltimitMovement along with parallax plugins like GALV Layers or VisuStella TileD it causes the events on the map to jitter compared to the steady/smooth parallax images.
It happens during diagonal movement, and especially when colliding with custom drawn slopes, like 45 degree angles or isometric slopes.
I tried a separate script on the old forums for a similar issue, called ‘DhoomUnroundedCharacterScreenPosition.js’ (from here: MZ - (Solved) Jitter on slow movement with parallax mapping | RPG Maker Forums) which fixes it mostly, a lot less jitter, but it introduces artifacts above the characters on the map (only with pixel movement plugins).
Enabling pixel perfect mode from another plugin, allows to see the visual artifact above the characters a bit crisper (it’s the “halo” above the head).
I tried to capture the flicker, I used video tracking to stabilize around the chest as much as possible, it’s not the parallax that flickers but the chest, this is just to show how out of sync it is.

Does anyone have any tips for smooth off-grid pixel movement using parallax layers? I’m struggling to get anything setup that doesn’t have an issue so far.
This is tested in a new project, fresh, no other plugins installed. I’d be hugely grateful!
