STEPS TO REPRODUCE
1.  Import two videos on separate tracks on top of one another
2.  Use the transform effect on the top video track to change its coordinates, move it to some other area of the screen, like the top-right corner
3.  Use the slide transition at the beginning of the track so the top video slides in, partially covering the bottom video
4. Note that at the end of its slide the video jumps which is very jarring. The effect is most obvious when the video slides in from the top to the centre. 

OBSERVED RESULT

The top video track jumps at the end of the effect, which is jarring. 

EXPECTED RESULT

The transition should be smooth with no jumping

I too can confirm I'm experiencing this when compositing SVG/PNG's above a video and using the Transform effect to position them. 
Then when using the Slide compositor/transition they "jump" in location before siding smoothly off screen.
