This is what it looks like in the GUI. In the program monitor, a part from the left side is cut off and inserted on the right, shifting the composition to the left.
Strangely, this only occurs with After Effects compositions. Otherwise, Premiere works normally. So it is probably not a graphics driver issue, or not even a Dynamic Link isse, more a problem in the interpretation of imported compositions.
