Anything else?

I believe I have found at least one source to this bug. I can fix this issue of avoid crossing walls not working by disabling "only one wall on top surfaces", but I'm not sure what the actual cause of this setting breaking avoid crossing walls is.

Confirming the problem. It does not depend on the printer model. Max detour length does not affect the result either.
The screenshot shows the resulting travels.

+1 on this. Just tested a bit and for me it has trouble with avoiding walls going INTO the infill. it avoids walls when the infill is done though. See image:

Only one layer shown. This is from a simple hollow pipe model.

Can also confirm that turning off "only one wall on top surface" or "only one wall on first layer" did not fix it for me. It did however rearrange where the infill started and ended.

Can confirm, having the same issue here. Just noticed as I'm printing here.

And goddammit the left clip got knocked off. Wow.

+1 Here. Exactly the same problem, once it's done with the walls and goes to start the infill, it ignores walls.

Not working in 2.1.1
Crossing top surfaces and making scratch on them as result.
Travel movements exactly the same ignoring this setting "Avoid crossing walls".

Apart from obviously the maintainers time, which is a precious resource, what else is required for this to be picked up for review?

After having realized how much of the stringing and artifacts this is causing, I was hoping to assist in sorting this.

Thanks in advance!!
