Layer discontinuity at section change with cura 5.4.0

[LabEqu 0]

Hello,
Sorry for my English and for the use of non-technical terms that I have not been able to translate 😉

 

I notice a problem on the layer located at change of internal section of my part and on a single layer (layer 66 on the attached project UMS5_test_bug1.3mf).
The 2 walls of this level 66 are not positioned identically to the previous or next layer, there was no problem with Cura 5.3.1

 

The outer wall of the part therefore shows a defect

This problem exists :

• with support (and with support UM Brekaways or another support)
• without support
• with other parts
• with other profil (but but more visible with profil "Fast" 0.2mm)
• with UM S5 or Um 3 extended

Cura 5.4 is known to be pretty buggy. Don't use it unless you really need any of the new features in it. 5.3.1 is fine.
