opacity effect bug
Shotcut version 18.12.23
Opacity effect at 0% applied to top layer (track v2) works correctly only if there is an active asset on the layer below it (track v1) .
If there is a “gap” or space on track v1 , or track v1 visibility is disabled, the asset on track v2 is still visible at 0% opacity. (You would expect it to be not visible, “black”, or “transparent” if working in RGBA)
