SUMMARY
After scaling down an image to 40% or below, using the Transform effect, adding a second Transform automatically makes the image blurry.

STEPS TO REPRODUCE
1. Add Transform effect to image clip (on timeline).
2. Scale down to 50% (or 20% for more pronounced results).
3. Add a second Transform effect (leave it on default).

OBSERVED RESULT
Image automatically becomes blurry when the second transform is added.

EXPECTED RESULT
That the image retains it's quality (until changes are made to the second transform).
