This odd behaviour has bothered me ocassionally. Seems like it just jumps out from no where when it likes. Decided to ask if someone else has seen this or knows reason for this?
Issue: Sometimes adding bump map causes very odd and rough shadow edges on surfaces. It kinda feels like random bug which is not happening everytime. I really don't know what is causing this. I can make it less visible making more dense mesh but that doesn't really solve anything, because the issue is still there. Been tweaking different lights/shadow settings.. nothing seems to help. Only removing bump helps. When it happends it mostly happends with noise bumps.
I made a little example image of the issue. In bw image you can see more clearly what is happening.
