Public bug reported:

When overlaying a video on top of another one using a custom layout, the
overlayed video shifts and moves around when the project is rendered.
In fact, setting a custom transparency screws things up too, as over
time the overlayed video with the custom alpha becomes more and more
opaque. This is reproducible every time.

I actually have an example video right here:

It's one of my own videos, and I think the bug is pretty funny, but at
the same time it's a serious problem. Anyway, here are the steps to
reproduce:

1) Import a clip.
2) Import another clip.
3) Set a custom layout on one of the clips so that it'll be smaller and off to the corner somewhere, showing the majority of the background clip.
4) Set a custom alpha too.
5) Make sure the clips in question last about 2 minutes long.
6) Render your video, and watch as the overlayed video dances across your screen (just like in the example).

I'm using Arch Linux, and Openshot version 1.1.3.
