Does having the extra overviews cause an issue? I assumed its better to have more than you need rather than less. Since at a factor of 64 or beyond they really cost almost nothing in terms of processing or space.
Here is the gdalinfo for one of my tiles.

Can you please try to add less overviews?
I guess 2 4 8 16 32 is sufficient in your case (well it depends on the dimensions of your granules). Maybe you can send a gdalinfo of a geotiff in order to take a look.

No only at near full resolution. So for this data that’s around 1:2,000. I see the lines anywhere from about 1:8,000 all the way down to 1:1.

I am creating an ImageMoasic from GeoTiff images created with gdal commands:
gdal_translate -co COMPRESS=JPEG -co PHOTOMETRIC=YCBCR -co TILED=YES -co JPEG_QUALITY=85 $infile $outfile
gdaladdo --config COMPRESS_OVERVIEW JPEG --config PHOTOMETRIC_OVERVIEW YCBCR --config INTERLEAVE_OVERVIEW PIXEL -r average $outfile 2 4 8 16 32 64 128
When viewing tiled mode in the OpenLayers preview at full resolution (about 1 meter) or near full resolution, I get these grid lines. This doesn’t happen when using single tile mode.
I found this post with a similar issue, but the solutions won’t work for me.
