Ady Tweaked the windows here also... If a flip is done perhaps on the section outside the dining room in the shot it could be flipped horizontally from Lando to Chewie and resized under the masking..

But then you won't see Lobot...

So how about flipping the shot where Lobot goes up the stairs it's an easier fix?

This sorts out Leia and Han not switching sides while walking but causes a problem at the dining room Door.

Paradox detected...

Ok conclusion on this....

As they leave the waiting room the first shot on their walk should be flipped horizontally for continuity.

The Shot where lobot appears the section outside the door to the dining room needs to be flipped and perhaps Han moved over to the left also a bit.
