I just discovered the most annoying bug on Earth, guys. I spend 30 minutes to figuring out why my layout looks strange (transparent rectangle around text). Then I saw this
.main-content-wrapper
transition: background-color .75s;
backface-visibility: hidden;
will-change: background-color;
My original code doesn't have this backface-visibility: hidden
!!!
Why Nuxt adds it? Both in Dev and after build.
