Tool Travels home after each layer
Using Prusaslicer 2.8.1
Recently, Prusaslicer has been adding useless travel moves to home after each layer and it's making my prints take longer.
I don't think I touched any settings and I've checked the custom gcodes and don't see anything related to this, other than G28 at start.
It's for a Geeetech but the printer isn't the problem. I'm seeing the traveling in the slicer's preview.

Not sure exactly why but its caused by (or at least it can be stopped by) turning OFF No sparse layers. Which is an EXPERIMENTAL setting anyway. When unticked it seems to slice correctly.

That IS strange. Had sparse turned on for years and now it's glitching? Devs should be aware.
Guess I'll go back to purge models for now.

There is this issue on the PS github https://github.com/prusa3d/PrusaSlicer/issues/13478 which on the face of it doesn't seem related as it looks tied to avoid crossing perimeters.
Except that your project is ALSO producing negative numbers in the gcode. Its not homing as those travel lines are way off the plater boundary. I'm wondering if it might have a common root cause in the code though, just that different combinations of settings loop through the same code function.
I'd open a new issue there with your project but also mention it in that one so the 2 get linked.
