How do I fix sprite jittering?

I want to have sprites align to the pixel/rendering grid but let the camera and crosshair move free from that grid, like how Enter the Gungeon handled things. Pixel rounding makes the sprites jitter when moving, but turning it off means the sprites don't align nicely. I've messed with scaling quality and such, but it hasn't helped.

You can try turning pixel rounding off, and round them manually with events.

For example, when the character stops, set its position to round(self.x), round(self.y)

Same for the camera - make sure its coordinates are always integer when it's not moving.

Thanks for the fixes, lots of combinations to try out.
