Lightroom 8.5.1
Mac Studio M1 Max
Macos 15.6.1
Steps:
1. Create new mask with a Brush >> the brush strokes appear as expected with a red overlay
2. Close Masking and go to Grid view.
3. Open same picture in Edit
4. Open Masking and select the brush mask >> the red mask overlay is one moment visible and then disappears. It does not come back by toggling 'Show overlay'.
Workaround:
Go to 'Compare' view and back to 'Detail' view, the red overlay mask appears again and stays visible.
I have tried resetting Preferences and reinstalling Lightroom, but this behaviour stays the same.
Hope this issue will be resolved in the next update soon. Greetings, Peter Vrijlandt
