Seams set to Rear become curvy instead of straight? [Curvy seams]
Description of the bug
Hi there. I usually set my seam position to Rear when I print upright models. The seam position in 2.4.2 usually follows the line segments that are at the rear position.
In 2.5.0, it seems to smooth the seam position over the z axis, creating curves where it used to be straight.
Could we have a toggle to go back to the old seam behavior? Or possibly to be able to tweak the smoothness setting?
I am attaching 2 images and 2 3mf files showing the difference

Hi there,
I installed 2.5.0 alpha 5 and it's still wiggly. Can there be an option to change back to the old behavior? Or possibly let the user change the smoothness factor
I'm in support of this suggestion, I'm still seeing wiggly unwanted seams in the alpha 3 version. They do not look good, it would be better if we could decide or just leave them straight, as they were in 2.4.x
I make lots of pots and containers, and the current seams are very unreliable when a perfectly straight line is desired. The new seam smoothing is wiggly for me in almost all cases. My current workaround is to manually and painstakingly paint a straight line. (A line drawing tool for seams would be stellar.)
Here is one of my production pots Sliced in the latest RC2. In previous Slic3r versions this seam is completely straight.
Attached is a quick and dirty example project. I'm surprised that more people aren't reporting this.
This issue is fixed in PrusaSlicer 2.5.0-rc2, so I am closing it. In case, let mi know.
Ok, in 2.5.0-rc2 we upgrade seam behavior, but I see it is not still ideal. so after crosscheck I open it again.... Sry
Fix the Seams please, just put them back the way they were in 2.4 and things will be fine. They are really bad in 2.5 and apparently going to be left this way in 2.6 if the alpha is anything to go by.
I'm stuck using 2.4 because of this. I would love to know why they felt they needed to be messed with in the first place.
