when applying brush in LrC, and mask is visible (o) you can see how the brush is applied creating vertical undesired lines. This look like a bug.

This looks like a jpeg where the color range of the image has been exceeded by the edit. With jpegs, over 99% of the color information was discarded vs a raw image so further edits must be subtle. This shows up most often with adjustments to the sky.

You don't show the entire Tool panel so it is difficult to see if you have Automask enabled. It looks like you do and the JPEG tiling is being painted in the very over exposed areas.

Thanks for the quick replies. Actually the picture was  .NEF, unfortunately I have removed that edit and cannot resend, but it is not the first time I see those patterns when applying brush. Yes, automask was enabled. I will resend a new example if it happens again.
