Mask problem

[weaselady]

For the past few weeks whenever i go to the mask and select a brush or gradient etc., the mask appears in green and will not go away.  It is not an overlay color.  It will even remain after I close the mask.  What have I clicked in error to get this?  Thanks!

Check this. Go to Preferences - Performance and disable the use of the GPU. Does that solve it?

[weaselady]

Unfortunately not.  I clicked on the overlay button (which I had selected as red) and it superimposed on the green mask with the result being brown!  I did a quit and restart after turning off  the GPU, but the mask remained green when LC restarted

How about a screen capture of your issue. If you should choose to do so, make sure the histogram is shown (it can sometimes give clues), and the Navigation window (that can also give a clue if it is very odd)

How's this?

So apparent GPU issue. Now on MACOS, that GPU driver is care of Apple during a MACOS update. Hence a inquiry

What is you MACOS version? (the number)

That Navigator pane looking all green overcast, just screams GPU driver. Either that or a corrupt preferences file.

[weaselady]

Thanks for your help so far. I've upgraded my Mac OS to the most current version, 14.3, and the problem continues. Considering your second suggestion of a corrupt preference file, how might I pursue that? My husband suggests perhaps removing the Lightroom Classic app, using AppZapper, and then re-installing a fresh copy of Lightroom Classic. What do you think?

Thanks for the input from individuals attempting to solve my problem.  I wound up trashing the preferences I had and now the problem has disappeared.  Whew!!

And in the Develop Module, over in the history panel. If you click on the first history state, how does it look? Does that Navigator panel go all green?

[weaselady]

The first entry in the History panel is ok as are several global adjustments I made to the image before I selected the Sky mask;  then the sky turned that bright green.
