System Information
Operating system: Win 10 18363.535
Graphics card: RTX 2080 Ti

Blender Version
v 2.81a (tested in new alpha and beta releases also)

Short description of error
termintor problem (pixelated pattern showing up when using bump map) showing up in cycles when using a bump map. this error has been reported in the past and stated to fixed in new versions, but upon testing these new versions. it looks like it is still present.

The issue tracker page linked does suggest that they've mitigated the problems in newer releases but the same thing occurs even in the 2.82 beta and 2.83 alpha so unfortunately, updating doesn't help.

Exact steps for others to reproduce the error
attached is the blender file - the error can be seen in the shirt. upon further testing, it can also be seen in the skirt when a bump map is applied to that also. so it doesn't seem to be the model or bump map.

Pretty sure we don't consider this a bug. Terminator issues were diminished but not entirely removed in all cases.

@brecht can you confirm?

@WilliamReynish Is there any simple solution to fix it, if it pops up?

@kynan.puru.watt add more geometry, reduce the bump amount are two methods.

Not a bug, the task is #68920 (Cycles: improve shadow terminator handling).
