Visual artifacts

Could it be the new squashed fly on the canopy feature that came in with the last patch?
As your screen shot is such low res, it just could be the fastenings on the side screen if you are in a spit - or something similar. If it's moving and turning with you it seems most likely to be part of your plane. Its impossible to tell. I think most of the little artifacts like that were dealt with a patch or two ago.
