I localized the problem to be `-co PREDICTOR=2`: Whitebox Tools produces bad result for GeoTIFF created like this: ``` gdalwarp -tr 64 64 -tap -r average -of GTiff -co TILED=YES...

I am getting invalid results also if I create input geotiff with gdalwarp and `-co BIGTIFF=NO` parameter. But actually the problem is with the compression DEFLATE (PREDICTOR=2). When I used...

Same problem is with `FeaturePreservingSmoothing` if input GeoTIFF has this compression: ``` COMPRESSION=DEFLATE INTERLEAVE=BAND PREDICTOR=2 ```

From https://gdal.org/drivers/raster/gtiff.html: > NBITS=n: Create a file with less than 8 bits per sample by passing a value from 1 to 7. The apparent pixel type should be Byte. Values...

I am ok with that and this issue is not a blocker for me. I only reported it so that you and/or other users are aware of it :-).

@Kanahiro thanks, but I can still reproduce it there pretty easily. Maybe Leaflet inertia-handling code could serve as an inspiration? :-)

@HarelM I can reproduce it also on your map. You must release mouse button immediately when you stop moving your mouse. It may need a little practice to master it...

@Kanahiro it is still reliably reproducible for me :-(. Moreover the movement after releasing the mouse is often in the altered angle.
