Created attachment 185619 [details] blocky artifact example SUMMARY Mesh transform exhibits a strange blocky artifact that looks sort of like faceted shearing when you move the vertex spline leg handles in certain directions, particularly toward the opposite vertex on the same edge of the mesh, and particularly along one of the canvas axes. Attached is a screenshot of this effect. Even though I pulled the legs to extreme distances to emphasize the effect, even short pulls of the legs quickly starts exhibiting the artifact, and can really shred up whatever you are transforming. STEPS TO REPRODUCE 1. Draw something (or open an existing image). 2. Lasso select a region. 3. Select transform tool. 4. Select the mesh subtool. 5. Move one of the vertex spline legs toward the opposite vertex on the same edge (usually this is at an angle that is already parallel with one of the canvas axes). OBSERVED RESULT Result looks blocky and sheared. EXPECTED RESULT Result looks nice and smooth (like with the other transform subtools).
