@aral basically, doing cleartype font rendering on a composited layer requires 6 colour channels (an alpha per channel), Webkit/blank uses 41 reply 0 retweets 0 likes -

@aral That means cleartype font rendering is dropped when an element gets a GPU layer. Position:fixed is a trigger in webkit (not blink)1 reply 0 retweets 0 likes -

@aral in Blink, if the element with the GPU layer has no semi-transparent pixels, cleartype is reinstated. Don't think WebKit does this.2 replies 0 retweets 0 likes -

@jaffathecake Nope. On a studio display :) Decided against using the fixed nav for the moment in any case :) Thanks for your help.
