Created attachment 108531 [details] Project and source image file showing the bug I found this bug when I was trying to fade out an image that had been scaled down. Steps to reproduce: 1. Open Kdenlive 2. Drag the image CRW_3215e_small.jpg into the Project Bin 3. Drag the image from the Project Bin onto track Video 1 4. Drag the image from the Project Bin onto track Video 2 5. Apply a "Position and Zoom" effect to the image on the Video 2 track. 6. Set the Size to 50% in that Position and Zoom effect 7. Right click on the image in the Video 2 track, "Add Transition"->"Composite and Transform" When the transition begins, the image in the Video 2 track moves a little bit to the right, both in the preview and in the rendered video. The same happens with the Composite transition.
happens also to me on 17.08.2 (Win64 version) i can confirm.
