Harmy,

I finished watching the workprint a second time. The only things I found were the following:

@ 10.55 In Jabba's droid torture room right behind C3P0 You see a machine going up and down which is blurred (maybe from motion) but the wall to the right of the machine also looks blurred or rubbed.

@ 11:07 Same scene the wall behind and above a Gamorrean Guard the wall looks blurred/rubbed.

@ 56:18 The Speederbike scene Lukes face really pixelizes for a brief second.

That's it, I could not find anything else that stuck out to me.
