P: Panorama Photo Merge not working (Windows - with Custom Scale Factor)

I have just updated and tested the panorama merge, and can confirm the issue has been fixed. Thank you very much for the help.

Lightroom Desktop 2.4 was released today and contained a fix for this issue. Please update to 2.4 and verify that you are no longer seeing the issue. Thank you!

Thanks for all your help tracking this down!

I can confirm the custom scaling is the issue as well, just disabled my custom scaling and the panorama merged flawlessly. 

I suspect your custom scale factor triggers the problem. Trying to see if I can get it to happen here.

Here are my display settings, I'm using a Dell 4K (3840 x 2160) display with 130% custom scaling.

What do your display settings look like?

Mine look like this:

Thanks, that's a pretty solid lead on what causes the 'hang'. Now to try and figure out how we got into that situation 🙂

I have done that now and got the following after only running the app and starting the panoramic:
