Quite strange bug/glitch

Hey all, this is my first time using reshade, so maybe I just did something wrong but I'm not sure exactly. I'm using reshade for Rainbow Six: Siege, and when trying to update settings and creating a new preset/profile it makes a little window in the top left corner where it shows a smaller image of the game. It makes it almost unusable and I'm wondering if there is a fix for this. Thanks in advance!

I have had the same issue since Reshade 3.0 so I have been stuck using SweetFX2.0 + Reshade.

I don't understand what causes this, I have nothing else hooking the game aside from uPlay overlay as you need that and I'm sure someone would have noticed by now if it was a uPlay wide issue.
