0. Load image with pronounced moiré into develop module and reset correction brush
1. New brush, all zero except for moiré, set e.g. to 25
2. Draw some brush strokes
3. Change moiré slider to a slightly different value (important)
4. Switch on mask overlay
5. Switch off mask overlay

Result: Moiré correction is no longer visible for this brush pin. Even switching to another picture and back does not help. The only way to bring it back is to restart LR, or to select the pin and slightly change the moiré slider.

The noise slider seems to be affected similarly. The other sliders seem not to be affected.

The bug is repeatable by selecting an existing pin and going to step 3, i.e. change moiré value, overlay on, overlay off - and the moiré correction is gone.

LR 4 final 64 bit Win7. Video: An old NVIDIA GeForce 7600 GS with up-to-date driver directly from Nvidias site (version 8.17.12.9573 from 09.02.2012).

P.S. Seems to be a display refresh problem only. Exports in this state are OK, the preview image is also OK (e.g. when switching to loupe view) - only the develop module display seems to be affected.
