If I set low resolution sprites in Factorio graphic settings, the container machines are jumping while working.
Here is a demonstration: https://imgur.com/a/jrhC7Xk
The problem is with graphics/entities/low/crating-base.png file in the mod: its lines are slightly misplaced on subpixel level.
When I resize graphics/entities/high/crating-base.png to 50% with bilinear method and replace original low/crating-base.png file, the problem disappears.
Please fix this. Thank you.

This is an issue related to the incorrect alignment of some of the assembler's frames in the entity's spritesheet. Not sure hot to resolve it in a clean way other than refactoring the graphics. Only happens in low res

To me, it helped to resize graphics/entities/high/crating-base.png to 50% with bilinear method and replace original low/crating-base.png to fix this issue.
Used XnViewMP to do this, but almost any image editor can select resize method.

I suspect this issue is gone in 2.0 entirely, since I deleted the low-res sprite and the game will automatically create them on load if you have “Medium” res sprites enabled.
