you can see many failures when on try:

I verified that adding a fuzzy-if allows this to pass:
fuzzy-if(/^Windows\x20NT\x2010\.0/.test(http.oscpu)||azureSkia,1,1500) == global-alpha.html global-alpha-ref.html

adjust filters to allow test to pass

I would like to fuzzy-if and leave this open until there are dev cycles to look into this

The leave-open keyword is there and there is no activity for 6 months.
:lsalzman, maybe it's time to close this bug?

This just looks like a slight different in rounding when certain types of blending are used (only off by 1 increment). Given that we're already seeing this with Skia, I think it is reasonable to just leave the fuzz in place and call it good, given that this bug is not being actively investigated further.
