P: Odd pointer behavior randomly appearing in LRC 12.3

Hello,

 

Working with LRC 12.3, I've noticed an odd behavior of the mouse pointer a number of times now, but I can't really figure out the exact conditions and how to reproduce it (yet). I'm posting here just to see if anyone else is experiencing this.

 

For example:

  • when I'm zoomed in, the mouse pointer only shows the "Hand" symbol (to move the zoomed area around) while I make movements (with my mouse); when I don't move it, it reverts to the normal pointer.
  • similary, when I'm using the Brush with a local adjustment, it only shows the brush as pointer while I move it; when I don't move it, it reverts to the normal pointer.

 

I hope this description makes sense.

 

My system is a 2019 27" iMac with 40GB memory, Radeon 580X 8GB. If it's of any importance, I'm running the iMac's 27" screen scaled, at 2880 x 1620 instead of its native 2560 x 1440, but this behavior is new to Lightroom Classic 12.3 and did not occur in version 12.2.1

On Lightroom Classic 12.3 running macOS Ventura 13.3.1, the cursor will continuously "flicker" back to the default macOS cursor in the Develop module whenever the cursor is moved over an element that changes the cursor to something else, such as:

  • the magnifying glass icon when hovering over the image
  • the cross icon when hovering over the Tone Curve panel
  • the scroll hand icon when hovering over number values
  • the double arrow icon when hovering over the histogram
  • any of the crop tools (Crop Frame Tool, Straighten, etc.) when hovering over the image

During this time, Lightroom may also have prolonged high CPU usage.

 

The steps to reproduce this bug are:

  1. In the Library module, select an image, then enter the Develop module.
  2. The bug will not appear at this stage. Cursors will appear normally.
  3. Return to the Library module, then enter the Develop module again.
  4. The bug will appear and the cursor will flicker back to the default macOS cursor.

 

The bug will temporarily resolve itself if the source in the Library module is changed, either by changing the library filters, or by viewing a different folder or collection. The bug will reappear when you enter the Develop module, return to the Library module, and then go back to the Develop module.

 

The bug doesn't appear in the Library module or in any other module; it only appears in the Develop module. It also doesn't affect the actual functions of the program—all the tools will continue to work as intended. Aside from the high CPU usage that may present itself, it's not a show stopper (but is very annoying to work with).

The first thing that you should try is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue.

Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

Another step is to try to reset the Lightroom preferences.

It's recommended to backup your preferences before you reset the preferences to the default settings:

Just tested: both the flickering cursor and the high CPU usage no longer appear when setting "Use Graphics Processor" to "Off". The issue returns when it is set to "Auto".

 

I am using a 13-inch MacBook Pro (2020 model, 4 Thunderbolt 3 ports) with Intel Core i5, 16 GB of RAM, 1 TB SSD, and Intel(R) Iris(TM) Plus Graphics with Metal acceleration.

Everything is up-to-date (Apple automatically delivers driver updates, and there's no manual process to install them).

Same here using the latest LR version on a 2017 iMac, on 15mb DNG files captured using the ProCamera app on an iPhone 11 Pro. Using Lightroom there's slower performance, flickering pointer, iMac fan making a low noise. I also have an issue now with not being able to update my folders using Lightroom, because I get a message "there are no photos in the folder".
I may have to roll back to 12.2.1.

With regards to the flickering pointer, I reported that here:

Would be great if you could add your "me too" there.

Re Flickering ponter, I only see it in the Develop module and reported this internally some time back.  The steps to reproduce on my Mac Studio Ultra, MacBook Pro M1 Pro, Mac mini M1 and 2019 MacBook Pro (Intel) are:

1. Launch LrC and switch to Develop module
2. Quit LrC
3. Launch LrC (app should now be in the Develop module)
4. Switch to Library module
5. Switch back to the Develop module

Moving the cursor across screen causes it to flicker between arrow and zoom.

I reverted each of the computers to LrC 12.2.1 as a sanaity check, and the issue can't be reproduced. Nevertheless, I updated to 12.3 again on the M1 based computers as I can work past the flickering cursor. I've left 12.2.1 on the Intel system to allow easy comparisons. 

 

It would be helpful if you could check whether above steps trigger the flickering cursor on your system.

Thanks for posting. Interestingly, when I quit LRC 12.3, and then reopened it, I didn't have the problem with the pointer flickering or the Jekyll and Hyde behavior of the pointer.

Thaks Alex, I did. But after quitting and reopening LRC 12.3, I didn't have the problem of the flickering pointer or the fans accelerating.

See my response in the other thread and check whether the steps I provided result in the flickering cursor.

 

Note that posts relating to the flickering cursor in the other thread may be merged into this thread for easier tracking.

I should add that I did quit LRC 12.3 while having the Develop module open, and then reopened LRC, but didn't use the Library module while I edited an image or two (15mb DNGs), even using Denoise on one of the two images.

1 - Edits are not required. You just need to follow the steps I provided above. 

 

2 - Next, disable the GPU and repeat the steps I provided

 

Report what happens for each of the two test cases.

Thanks for the hint that the switch between Library and Develop has something do to with the flickering mouse pointer.

 

Findings:

 

  1. I seem to be able to reproduce this now, by simply switching back and forth between Develop and the Library "1-up" view (keyboard shortcuts D & E respectively) TWICE (ie. no exit in Develop & restart required).
  2. it doesn't happen with GPU support off
  3. it begins to happen as soon as GPU is used "for display only"

Ian, I followed your 5 steps, and after the 5th step when I'm back in the Develop module, the cursor flickers between the pointer and the hand. I tried this with different views (Fit and 66%) and the flickering happens in both. I've yet to try the 2nd procedure you requested which is to turn of the GPU.

Ian, I just tried that 2nd test, the one where I turn off the GPU and then quit LRC 12.3 with the Develop module. Once I open LRC, and then choose the Library module followed by going to the Develop module, the pointer doesn't flicker or bounce between the hand or enlargement (magnifier) and arrow pointer.

I've been using Lightroom Classic for two days now (mostly re-linking my folders of images listed in the Develop module to my image folders in Dropbox 172.4.6706 now residing in the CloudStorage folder in Library on my iMac using the current MacOS), and the flickering pointer and or accelerating fans have disappeared, even after setting my Graphics Processor back to Auto in the Performance module of Preferences.

Mysteriousbut I'm happy!

Glad I found this post. I'm experiencing the same bug on a 2017 iMac with an AMD Radeon Pro 580 running Ventura 13.3.1 (a). When I don't use the graphics card, the problem goes away.

Hi, ich habe vor ca. zwei Wochen endlich auf das neueste LR Classic 12.3, Mac Book Pro 16 " Ventura 13.3.1 upgedatet. Seitdem hüpft/springt/wackelt wenn ich Pinsel oder Reperatur auswähle und das Objekt einkreisen oder eine Maske ziehen möchte immer zwischen dem ausgewählten Tool und dem Mauspfeil hin und her. Ist das normal?

Anyone having the issue of the healing brush constantly turning from the healing brush circle to the mouse pointer? It's very distracting.
