Nope, no reshade or even any of the tweaks that AMD has built in. Turning off antialiasing does not get rid of the black oval, either, though again that one is minor enough that I don't mind it much.
Just turned on AMD's antialiasing after double checking that SWTOR's was off and it looks fine at first, but there are some problems:

New visual artifacts on portraits (and probably other things too) and a weird glow around the outside top and left sides of the window. Turning bloom off eliminates the glow, but I don't really want to play without bloom so that's a no-go. I've tried a few of the different modes and they all do this, so it seems like I'll just be sticking with SWTOR's medium for now if I want to play GSF. Doesn't seem likely to get a driver update that fixes this as it's been going on since LotS dropped.
