Label of Polygon showing outside of polygon using a WFS

[RadMagnus]

What is the bug or the crash?

Having polygons labeled, panning around and moving to the edge of a polygon can lead to misleading labelling.

This is expected behaviour. All labels are within their polygons:

However, if you pan to the right a bit, you might get the label (here Kempen) within the wrong polygon.

I suspect the issue here is that the Polygon of Kempen does extends to the east but only north of where the label is. As you can see in the green outline.

Steps to reproduce the issue

Import WFS:

• https://www.wfs.nrw.de/geobasis/wfs_nw_dvg

Load Layer:

• DVG2 Kreisangehörige Kommunen und kreisfreie Städte

Label Layer:

• single label based on GEN

Zoom to Kempen:

• 321387,5694751 (EPSG:25832)
• Pan to the right, to recreate the screenshot above.

@RadMagnus you must activate the right option

3.18.0-Zürich

also update to 3.20.1 as 3.18 is way too old and also unsupported.

I was not aware of that option, thank you! Marking this as closed and tell my IT-Department they should update more frequently 😄
