P: Masking panel entering values manually or via arrow keys no longer preview until Enter is pressed

Thanks for the clarification Rikk.

I've reviewed our internal ticket, and it is still shown as open and scheduled for an upcoming release. If it is working for you, that is great, but I would not consider this thread closed until Engineering confirms. 

Let's see what Adobe (aka Rick Flohr or equiv) says about this.  If they actually realized that it was fixed, it should have been in the release notes.  Maybe left off mistakenly?  Or they didn't realize they fixed it? 

Yes, even though there's no mention of it in the release notes, it's fixed. I guess they didn't regard it as a serious bug. There may well have been other similar things fixed. 15.1.1 fine on my W11 laptop and desktop PC. Good that it's fixed.

I too can confirm that on 15.1.1 it is fixed.
Both increasing the values with arrow keys work.
No more weird increments and changing values immediately shows the result again.

Well just installed 15.1.1 and it appears that this issue is fixed.

When the bug fix gets released, Adobe will post in this thread and update its bug status to Fixed (see the top post for the status).

According the Adobe's release notes the answer is no.   I don't care about the 2 items that were fixed since they don't affect my workflow.  So I don't plan to update.

So the latest LrC 15.1.1 has been released. I'm reluctant to try it. Anyone established if this fixes the masking panel values bug?

I knew something odd was going on. I too have this exact issue. Seriously hindering my workflow a ton.
