Problems with transitions about openshot-qt HOT 1 OPEN

This is a known bug and in the queue to be fixed in a future release(note: there is a v3.1.2 in the works to be released but unfortunately this fix is not in it at this time).

A workaround for this would be:

1. Drag the first image on Track 5.
2. Drag the 2nd image on Track 4.
3. Overlap them as if they were on the same track.
4. From the Transitions tab drag the Fade transition or whichever one you want onto the clip on Track 5. Adjust the left edge of the transition so it is only covering passed the 1st half of the clip on Track 5. This will achieve Fade Out.
5. Do the same for the clip on Track 4 but adjust the right edge of the Fade transition so it only covers less than the 1st half of the clip. This will achieve Fade In.
6. Preview and you should see the transition working properly.
