So yeah basically the issue above, Ryyz and some in-game lightning gets this flickering white square (if I zoom in, you have to be close) that can only be solved disabling the resolution graphic pack. Did not find this issue reported and I dont know if it is just me, what do you guys think?
Tried reinstalling the graphic packs, deleting shader cache and also trying other resolution options like 2k and 4k but the upscale seems to be the problem. Collectible sparkle effect seems to have the same problem but less noticeable.

Using Cemu 1.14.0c, XCX EU Ver.
Specs: Gtx 1060 6gb - i5 7600 - 16gb (8 + 8) RAM on Windows 10 Home
Driver ver. 416.34

Thanks for your attention
