What does the "C" icon mean in PhpStorm?

Question

phpstorm

Hello!
Tell me, please, what does the "C" icon mean in front of PHP files, which constantly changes to the php icon and back to "C" in the process of typing?
Question 2: how to turn it off? This blinking is really annoying.
OS: Mac OS X. Standard dark theme.

2. check for eap. if the blinking persists, feel free to go to them in the tracker. they are quite responsive guys.
You can also try changing the view in the file tree from Project to Project Files.
