Being a web dev is SO WEIRD sometimes.
I'll do something totally normal like have a blue background and it'll be fine except one browser is all "I'm gonna make that pink lol" and the fix is to move the background by 0 pixels.
This isn't even a joke.
Safari has an issue with filter: blur() and color interpolation. It rendered a blue background as pink. The fix was to add translate3d(0, 0, 0) to promote into a layer.
