Hello, I would like to ask someone for advice on the problem of aircraft and airport lights. They do mainly airplane lights (mine and AI) and at some airports. The lights seem to blink and make the most common square texture around them. I do not know how to describe it better. Look at the pictures https://imgur.com/a/rTv0s Thank you very much for the advice and sorry for the bad English, I use google translator. Thanks
