Print String to output log causing huge FPS drop

I am encountering a very strange bug in UE 4.8. When I print string to the output log while the output log is scrolled down all the way, I am experiencing a huge FPS drop. The frame, game, and GPU values are all the same high number (~45 ms), while the Draw will stay at the usual 4 ms.

Here is a video demonstrating my problem: - YouTube

Hi Jamendxman3,

I tried to reproduce this in 4.8.2 and only experienced a 10 frame drop when I printed to the output log when triggering an event, specifically touching a block with a character. Also, I did not see any varience whether I scrolled to the bottom of the log or not.

Could you try to reproduce your results in a simpler scene; one without trees and leaves animating in the background and see if you have similar results. If not, then we can narrow down the vegetation as a factor or rule it out if you still experience the bug on your end without the trees animating in the background.

Thanks.

I just tried to test this again after making no further changes but was unable to replicate it, I suppose it was a one time bug. I will post back with the questions you had if I encounter this bug again.
