Position and zoom produces a black square
Apply position and zoom effect, all goes well till I add a keyframe. Then the project monitor window goes black and stays black.
Screengrab from Windows7 (same issue on Win10):
Position-Zoom_Black_Screen
AppImage 19.04.0 works.
Here the issue on Linux: https://forum.kde.org/viewtopic.php?f=265&t=160451
