Hi all,
I have a layer with closed polylines. Some of them almost fully overlap
(but not quite).
The problem I witness is that for some couple of polylines, only one of
the two is rendered. Depending on the bbox, it can be one or the other,
but never both.
Here is an example of what I see :

As you can see, the second one is zoomed out and the polyline is shown.
I over-simplified the style to rule this out, so it now reads :
- name: 81
rules:
- zoom: [13, 17]
filter: ${layer IN ('81')}
symbolizers:
- line:
uom: meter
stroke-color: '#000000'
stroke-width: 0.1
I checked in the log (GEOTOOLS_DEVELOPPER_LOGGING level), but saw
nothing wrong.
I manually ran both queries that I found in the log againt my PostGIS
database, and both did return all the geometries (even the one not
rendered).
The only thing that suprised me was :
2018-09-19 11:56:12,816 DEBUG [org.geotools.rendering] - Style cache hit
ratio: 0.98 , hits 49, requests 50
And then :
2018-09-19 11:57:39,422 DEBUG [org.geotools.rendering] - Style cache hit
ratio: 0.9655172413793104 , hits 28, requests 29
So in both cases, one hit less than requests.
Does anyone have an idea of what could be happening here ?
Thanks for helping !
Regards
