Running master:

I tried encoding a 1920x1080 RGB TIF, with command line parameters:

-t 128,128

and the resulting image has severe image artifacts. It looks like all pixels with x value greater than 128 are just clamped to the value at 128.

This is a 16 bit image, by the way.

I checked older commits, up to 2 years ago, and this bug is also there. So, this has been broken for quite some time.

Well, this turns out to be a problem with kdu_show. OpenJPEG works just fine.
