            Bug ID: 421721
           Summary: Transform effect displays 100% image size, even when
                    it was changed with "fit to width"
           Product: kdenlive
           Version: 20.04.0
          Platform: Manjaro
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: User Interface
          Assignee: j...@kdenlive.org
          Reporter: shina...@gmail.com
  Target Milestone: ---

SUMMARY
Transform effect shows incorrectly 100% after image was changed with "fit
to..."

STEPS TO REPRODUCE
1. I drag and drop an image into the timeline. The image has for example 1000px
width, while the video is 1920px wide.
2. I add the Transform effect to the image.
3. The size shows correctly 100%, as the image only takes half of the video
size.
5. I click on "Fit to width". The image takes now the whole video size.
6. In previous versions the displayed image size in the transform effect also
changed to about 50%. However, now it stays at 100%.
7. Now when I change the size from 100% to 101%, suddenly in the preview
monitor the images makes a huge change from 1920px to suddenly 1010px. This is
a big problem when I work with keyframes and want to animate a change of size.
8. The only way to display the correct size is to click on "Adjust to original
size" and then afterwards click on "fit to width". Only this way the correct
size is displayed in the transform effect.

OBSERVED RESULT
The displayed size of images is always 100% after clicking on "fit to width",
even though that's not the case.

EXPECTED RESULT
The displayed size should change when I click on "fit to width", according to
the image change in the preview monitor.
That's how it was in previous versions.
