Nausea? from PBE set 18 client

I'm unsure if it's the brightness, sharpness, uncanny valley of the not-quite-league client, but the new set makes me feel like I want to throw up.

I was wondering if any other photosensitive or regular people were feeling that way for the current beta.

I wish I could pin down the exact reason, but it's more of the overall appearance, even windowed and shrunk down.
