See the attached test.  When I size my browser window to an odd number of pixels, on a Retina display, the canvas has blurry edges, probably because is position is not an integer number of pixels.

Shouldn’t this be “replaced content should paint with pixel snapping”?
Comment 2 Cameron McCormack (:heycam) 2021-12-14 14:41:32 PST
Yeah.  Subpixel layout is fine, but painting should be pixel aligned.
