I been trying today switch on work to new 2.81 - what I found is that snapping stop working through objects when X-Ray value = 1. On <=0.999 it work ok.
I also checked 2.80 and current alpha 2.82 - thing work in same way. Is that some " new conception " how things should work or this is bug? I ask because I skipped 2.8 so don’t really know adout all " conceptual " changes.
Update.
I talk about this (on GIFs cursor in wrong sosition because of different monitors… )
2.79
2.81 ( same in " clear " version without any customizing )
