Created attachment 170638 [details] Video showing bug SUMMARY When I apply on the same image two transform (one scaling down to 25% and one doing nothing), the quality is suddenly super bad. STEPS TO REPRODUCE 1. Start KDEnlive and import in the project a png image (see attachments) 2. Insert the png in the timeline 3. Add to this new clip an effect Transform, and set scale to 25%. Observe the preview in reasonable quality. 4. Drag a second Transform on the object. Observe how the quality suddenly dropped (in both preview and exported video) OBSERVED RESULT Bad quality EXPECTED RESULT No quality loss when applying an identity filter.
