Hello, this bug is present since the early days of MSFS2020 and I’m wondering why nobody sees it.
Look at the engine exhaust heat of ENG2 while flying, its a straight line and seems more or less realistic.
Now look to ENG1, the engine heat follows a “spiral” rotation and also clips through the wing. It’s also wider and more “nervous”.
The clipping problem was one of the first things I noticed after launch…
Here is a short comparison video:

Am I really the only one who cares about this? 
Hope this bug will be addressed, would be a easy fix…
