If I decide to use newer development versions of Dolphin, I'll stick with 1440p (via VSR), no AA, and 4x Native Res. in OGL; just like I do in DX12.
Alright, I think we know what the problem is.
The issue is do we break OS X to fix AMD, or do we implement a wonderful hack to try to fix both because we're blessed with such great drivers? /s
This will be figured out eventually. Until then either use Direct3D, or turn off MSAA.
EDIT: Stenzek already might have an ugly fix. We might have a PR soon.
I'm uploading a Dark Souls II: SOTFS PvP video right now; I'll test it once the video is done uploading.
Alright, I just downloaded pr-3757 and tested running FE: PoR in OpenGL with MSAA 2x enabled.
It worked and there were no errors.
Cool! I'll mark this bug as fixed in PR and we can decide what to do with it.
