Seems like unfixed body lean animation is right, (sv_showlagcompensation 1; sv_lagcompensateself 1)
But may be it is csgo bug and real server hitboxes are not like blue one
maybe thats why people was killing me when i was on unscannable wall
More weird is that bug appears only when i am using left/right antiaim, when it is backwards all is ok
try testing this again on an actual server, afaik local servers are inaccurate
