First clip follows like it should. Second clip DOES NOT.

Seems again the wrong Geometry issue... i have openend bug segnalations for this... this happens to me on 2 composite transitions at the same time.. the second transition is moved vertically by the difference from "main" vertical transition... also i can see the issue that make the rectangular RED border with wrong proportions (not the porportions of flag)

i'm still waiting to be solved... BTW .. are you using ENGLISH/US version of Kdenlive ? (your decimal point is "," or "." ?)
