Short description of error
quad remesher badly deforming the mesh

Exact steps for others to reproduce the error
The blender file perform the quad remesher in object mode. You will notice how pinched part of the mesh is almost cut off. The default remesher modifier is doing great job here, you have to increase the octree depth

I have been having crashes with a mesh more 100k and the system hangs for like 20 min but this will be for another report, one at time :)

Left original, right remeshed:

The result is quite bad indeed. Not sure if there is a good way to solve this. Leaving it up to @ZedDB to handle this.

I can reproduce this issue with the standalone QuadriFlow program, so this is not a bug with the blender code.
I've filed a bug report for QuadriFlow here: https://github.com/hjwdzh/QuadriFlow/issues/43

Changed status from 'Confirmed' to: 'Archived'

This is an issue with the Quadriflow algorithm itself that most likely can't be solved for a specific case in the Blender side. The issue was also reported in the Quadriflow repository in https://github.com/hjwdzh/QuadriFlow/issues/43, so you can keep track of the progress there.

This is sounds like known issue to me, this is not invalid, i believe you know better...
