[QGIS-Developer] QGIS 3D: Fails with large DTM image

[C Hamilton]

QGIS 3D has a lot of potential and works well with small DEM data sets, but
when ever I try it with a large DTM image I just get a white screen. I tend
to work with large DEMs (50000 x 50000 pixels and larger) and I would love
for this to work with it properly.

Do you have any ideas why this is the case? I have tried this with an
AIG/Arc/Info Binary Grid image as well as a GeoTIFF with overviews.

OS: Windows 7; QGIS 3 Version: 2.99.0-238

Thanks,

Calvin
