The behavior described in the comments might be actually happening...
sorry, no time to
look into it right now, we have the JDK11 code sprint incoming and all
spare time is going there.
I checked the ticket tracker, found no bug report about it.
I would be useful if someone could verify, maybe using a built-in demo
Fixing it right now might help, but it will take many years before older
versions of GeoServer
out there are upgraded, we get a surprisingly high number people running 5
years old versions of GeoServer
asking questions on the list.... just saying, even if one rushes to fix it
now, that code in QGIS might
not be lifted anytime soon (but it could be made configurable I guess?).
Also, in GeoServer WCS 1.0 normally uses overviews when available, but of
course the layer
might not have them, or be a mosaic of many files. That said, the WCS being
queried is not a GeoServer,
not sure how it might work.
Finally... any chance QGIS could be using WCS 2.0 instead? The 1.0 and 1.1
protocols are ancient and pretty clunky,
WCS 2.0 is so much better from all points of view.
In fact, I believe that WCS 1.0 and 1.1 have received little to no
in GeoServer for the longest time, I'd venture to guess very few care about
WCS 2.0 is instead receiving interest and more care, likely because it has
been chosen by INSPIRE
for raster download services.
