[BUG LOGGED] Performance Decrease when Using Pop-Out Panels

I have done a search but have not seen any decent solutions for this issue.
What would cause or is causing the issue when you pop out a window to another screen it causes between 7fps and 50% decrease in frame rate. IF I pop out a settings windows such as weather or camera it decreases by 5-7fps. Others in discord have tried the same thing with the same results. If you use an external app with sim connect no such fps hit is noticed (vfrmap or flight companion).

Do you have any add-ons in your Community folder? If yes, please remove and retest before posting.

No difference

Are you using Developer Mode or made changes in it?

Used developer mode to display the FPS counter
