Is there any way to fix this? Perhaps there's a setting in ReShade? I've tried 4 versions of ReShade, and this problem only occurs in versions 6.6.2/6.5.1 and 5.9.2, but not in 4.9.1.
If I change the size of the game window very aggressive, I manage to reduce this rectangle by half, but it still remains. One time I even managed to make it semi-transparent. The game is Sword of Justice (F2P on Steam...) and I think it runs on DX12.
Funny thing is that the box is NOT here if i only enable Curves filter, but every other filter will trigger it.
