What about increasing air circulation? The idea would be to stir up the air more, hopefully, to homogenize the air mass between the projector and screen.
It might take a lot of fan power to do this. You might have to create a virtual windstorm. In that case, you would be better off leaving well enough alone.
We, as operators and technicians, are much more tuned in to minor problems than the average public. 90% of your customers will probably never notice. 90% of those who do notice probably won't care. Yes, if you can solve the problem, you should fix it but don't kill yourself for such minor things.
If adjusting the HVAC can solve this, do it but, unless you are getting complaints, don't worry about it.
Schlieren has been visible on the screens at Tinseltown, here in Erie, ever since the building opened. Only a handful of people have ever noticed. I'm one of them. The only other people who I know have said anything also worked in the theater. The majority of those were projector operators.
Never has a customer complained in almost twenty years.
