P: Masking overlays do not always appear (Mac)

I'm having the same problem - updated to LR 8.3.1 yesterday and masking overlays stopped showing.  Went back to previous version LR 8.2 and masking overlays show again.  So the issue is with the latest update.  I hope this bug can be resolved soon so that I can update the software.

Hi. Latest suggestions to solve have not worked. There is still an issue with the masks not appearing as they should. Seems to be a lot more people seeing this issue since the latest update. Surprised a company with the firepower of Abobe can't replicate this. 

It's clearly a bug. It started with v8.3.

New masks will initially display correctly, with overlay. But as soon as you exit and re-enter the masking mode, the overlay just flashes briefly and is gone afterwards. 

MacBook Pro Max M3

macOS Sequoia 15.5

Lightroom v8.3.1

Steps to Reproduce:

1. Open lightroom.

2. Select a photo from the grid layout.

3. Press M to open photo with the Masking tool panel.

4. Create a Radial mask by dragging the mouse. Notice that the red (default color) overly shows.

5. Press E to open the Edit panel.

6. Press M to reopen the Masking panel.

Expected result:

red overlay shows when hovering the mouse over the overlay when the Masking panel is open.

Actual result:

overlay is no longer showing.

I've made another example with a different picture

Hi Srishti, 

This seems to have been broken since 8.3. 

This is reproducible with simple files DNG, JPG, etc. We're seeing people on reddit, here, and elsewhere reporting this problem.

Considering the volume of bug reports I see where the immediate response from Adobe is some variation of "We were unable to reproduce this bug internally", when I, an unpaid and paying user am able to reproduce the same bug almost instantly, it suggests to me that there is a serious systemic issue with Adobe's internal practices. Whether that's just general lack of skill from those in charge of reproducing these bugs, or gross oversights such as only testing on a very narrow range of hardware and specs, it should not be the case that a multimillion dollar corporation is consistently unable to reproduce bugs that an idiot like me with a laptop and phone can.

Hi,

1) All files, all types of masks.

2) Mask overlays have probably been unpredictable for the better part of 6 months, but in the past 1-2 weeks they've become impossible to work with and fail 90%+ of the time.

3) Unfortunately all of my raw files are quite large (50mb+), I'd be happy to set up a screen sharing session or whatever required to demonstrate the issue, can also record a video as long as I have somewhere to send it over to.

How do I revert back to an earlier Lightroom version?  My masking overlays are also disappearing and this is the main tool I use on lightroom.  If it doesn't work, I may as well quit LR completely and find a different editing program. 

Edit: after reverting back to Lightroom version 8.2 the problem is gone.
