Hi, > If you rotate by exactly 90 degrees, this is always done with > INTERPOLATION_NONE, no matter what you select in the tool options. Perhaps this is the culprit? An offset seems unavoidable if the transformation is performed without interpolation. So perhaps all we need to do is to remove this optimization (which is supposed to speed up rotations by multiple of 90 degrees)? Peter, can you try to remove that code in app/core/gimp-transform-region.c (line 208 and 209) and check if that fixes your test case?
