Hi Pedro,
by the looks of the image, I see you’re issuing a GetFeatureInfo with a 50
to 100 times oversampling factor
(1 pixel is represented as a 50x50 to 100x100 pixels), small numerical
issues are inflated significantly in that scenario.
I’m not aware of a magic “make it work” flag, code analysis and changes
seem the best way to approach this.
See this guide to get it done:

Hi users.
I´m having trouble when i use GetFetureInfo against a image mosaic whose
granules are in two different projections (EPSG:25830 and EPSG: 25828). If
i click around the center of the pixel all woks fine, but if i click near
the border, i obtain the value of the contiguous pixel.
When all granules of the mosaic are in the same projection (SRS) all works
fine.
I´ve tested that cartografy is well georeferenced and the image that i
obtain from WMS is ok, the displacement only occurs when requesting
GetFeatureInfo
If i click at the center of the pixels, i obtain correct value:
When clicking near the border of the pixels, i obtain the value of the
contiguous ones:
For example, if I click at the border of a red pixel (value=73.23) i
obtain the value of the white one (value=-3.40) next to it:

In .properties i use:
Heterogeneous=true
HeterogeneousCRS=true
MosaicCRS=EPSG:25830
And at index file (SHAPEFILE) i have SRS field
Any ideas on how to correct this trouble?
Regards.
