Question

Histogram is cut off after switching users (macOS)

I haven't tested all the variables here so I'll just give the exact steps that allow me to reproduce the issue, but some things (like specifically using fast user switching) may not be necessary.

  1. Set up two user accounts
  2. Enable Touch ID on both accounts, using different fingers
  3. Make sure "Use Touch ID for fast user switching" is enabled on both accounts
  4. Make sure both accounts have been logged in to since last booting the system
  5. Launch Lightroom on either account
  6. Set the Lightroom window to fullscreen (🌐F / ⌃⌘F)
  7. Open any photo
  8. Open the edit panel and ensure the histogram is enabled (⌘0)
  9. Using fast user switching, switch to the other active user account
  10. Using fast user switching, switch back to the account with Lightroom open

Upon switching back, the Lightroom window will briefly reset its positioning, and in the process, position the histogram too high, causing the top section of it to be cut off:

Hi ​@Generous_view0D45, Welcome to the Lightroom Community forum! I apologize for the delayed response and for the confusion. Typically, we don’t move threads into bugs unless we can reproduce them, and as of now, we are unable to reproduce this issue. To better help you with this issue, can you send your system info and a screen recording of the issue? You can find your system info by going to Help > System Info, copying and pasting it into a text file, and attaching it here. The list is very helpful! ^CH

To be clear, my post was made to Bugs, and at some point in time after that, someone decided that while they had the time to move the post out of Bugs, at no point prior to that nor in the two months following that did they have the time to test what is a very simple bug to test, or even at least follow up in the most basic way.

As for your request for a screen recording, I find that rather concerning, considering that my steps clearly indicated that switching user accounts is necessary, and any screen recording would either only show the original, unbuggy state, or the final bugged state, which is already clearly visible from the screenshot I provided.

Respectfully, who the hell is moving these out of bug reports without even taking the time to follow up on the issue or mention if they're having trouble reproducing it?
