Cura 4.10 first-layer problem with skirt

[esopalumpa 8]

Hello,

 

Cura 4.10 damages the first layer if Build Plate Adhesion is set to Skirt. See attached screenshots.
Top: Build Plate Adhesion is set to Brim.

Bottom: Build Plate Adhesion is set to Skirt. As you can see the ventilation-grid is missing. It starts at layer 2. This does not work properly, you get a spaghetti-ventilation.

Check the Initial Layer Horizontal Expansion.  Make sure it is set to "0".  It's possible that Horizontal Hole Expansion is a problem but if the thin features show up on subsequent layers then the problem may well be the Initial Layer Horizontal Expansion.  I don't think there should be difference between Skirt and Brim though.  Are you using two different profiles with one set for skirt and the other for brim?

Ups, I forgot to comment, sorry
Yes, it was Initial Layer Horizontal Expansion and no, the profiles are identical except for Build Plate Adhesion Type.
