The inner face of cacti does not render if viewed from behind, where it probably should.
Redstone torches and such are only affected in Programmer Art.

Would this relate to MC-129481 with the improper water culling?
Although this issue is about the faces culling when they shouldn't, whereas the other issue is faces not culling.
I'd say it's closer to MC-60772.
Also affects spawners and leaves. because they are transparent blocks. see MC-169969
Attached a screenshot from Bedrock Edition, where this bug does not apply.
