Sometimes I experience display issues with geoTIFF in QGIS (also had this once in TatukGIS). Now i have a situation in latest QGIS running on Linux KDE. The image is kind of disturbed (s. example). If you move it it randomly gets different defects.

On another QGIS station it's shown perfectly. Also in other photo applications like GIMP, or even simple windows viewers.

What might be the reason? Looks like a rendering, or openGL issue or something like that.

The whole orthophoto is tiled and here's the gdal info about one tile as example:

    Add gdalinfo report of your raster, even better if you can put a small test image available somewhere. – user30184 Feb 13 '18 at 8:15
