How to reproduce

I created a lithophane stand with a 1 wall thick shell (for the thick layer lines aesthetic) and some things at the end to hold a swappable lithophane.

Actual results

Orca introduced multiple unnecessary seams which negatively impact the look of the print result.

Even worse, for the below cutout for the microcontroller it creates three loops per side for a total of 6 loops:

Expected results

I expected the wall to be one continuous wall instead of multiple separated circles.

Note: You'll get the result with 0.8 nozzle size and 0.9 outer wall width. Lithophane Box v0.zip

I've recently observed this behavior again. I'm puzzled that there's no reaction to this, it impacts stability and looks very heavily. Am I doing something wrong, that this is not a more discussed issue?
