Description

I have a GeoTIFF file that for some reason is rendered by multiple tiles of same content when zoomed out (see attachment). Zooming in fixes the issue.
For some reason it happens only with GDAL 2.0.0 or 2.0.1, but 1.11.x is not affected. It could be also a bug in GDAL itself although GRASS GIS 7.1 is not affected by this issue.

This was a GDAL problem. Fixed per https://trac.osgeo.org/gdal/ticket/6308 (will be in GDAL 2.0.2). Surprising GRASS wasn't affected. You're lucky I found this ticket by chance, so next time you suspect a GDAL issue, do not hesitate to report on GDAL Trac.

Thanks for rising it up to a proper place. From an end user perspective it is hard to understand if it is QGIS misuse of GDAL or problem with GDAL itself.
