Hi Jérémie,
Ah good to hear!
I'm not a big fan of this fact that line simplification is turned on by
default in QGIS. I believe that users should consciously turn it on if
they want it!
Your example shows that it can lead to confusion (understandably).
Good that it works now. Note that you can override this setting on a per
layer base in the layer properties - so not all layers need to have the
same setting.
Greetings,
Andreas

Hi,
I had simplification turned on, indeed...
I deactivated it :
- in the Options as you mention, so that it is deactivated for newly
added layers
- in my layer options (Rendering properties)
And it is ok now.
It makes sense that if the line is simplified the distance vary !
Thanks Andreas.
Jérémie.

Hi Jérémie,
Do you have geometry simplification turned off? See "Settings" -->
"Options" --> "Rendering" --> "Enable feature simplification ..."
Make sure this is deactivated (I think it is enabled by default).

Andreas

Tested too fast :(
Behavior is ok when zooming in, but still problems when zooming out
(whereas the entire feature is visible !).

Circles should follow the strokes generated with the tool "Points along
geometry".

Hi,
Thank you very much Nyall, this one was pretty well hidden.
With clipping unchecked, behavior is as expected for my use case.

Hi,
I'm using QGIS 3.10.
I tried to use only symbology to display a stroke every km along a
road.
The project CRS is 2154 (Lambert 93).
When adding a ""symbol line" with an interval of 1000 map units (meter
for 2154) - or 1000 meters at scale, same result - I achieve to
display symbols every km.
Problem is when I move the map or change scale, the symbols do not
always stay in place. They are sometimes misplaced.
I've been told that problem can be that the first node of the line is
not always the reference to calculate the intervals.
From the bottom of the symbol widget, click the "Advanced" button and
uncheck "Clip features to canvas extent".

You can find a GIF here that displays my problem :

Circles are symbols via Symbology.
Strokes are symbos on points generated vith the tool "Points along
geometry".
You can see that circles are not always at the same place as the
strokes.
Is it a "normal" behavior ?
Anyway as a user I would expect that symbols are always generated at
the same place from the starting node.
Thanks for your enlightments on this.
Jérémie.
