DTM from TIF not rendering shader unless zoomed in

Hey clan! First time that I have ever experienced this issue, and I tried to find a setting somewhere, with no luck.

I have loaded DTMs from TIF zips (DGGS IFSAR data), like I have hundreds of zoom level of 1:105600, the DTM shades properly (Color Ramp, Atlas, any..), at 1:110900 the grids blackout. That is in map view and 3d view. See attached images. Any ideas? The grids in question appear to have better resolution though the meta indicates the same resolution as adjacent grids that render just fine.

    That sounds like a bug. I suggest that you contact Blue Marble Support directly via email ( to address this issue. Please include a detailed description of your workflow, and a sample data set that can be used to reproduce the problem. Thanks.
