LRC問題Lightroom Classic 15.6 – All sliders jump to far left when clicked; handle doesn't follow the mouse cursor
Hi everyone,
I'm having trouble controlling the sliders in Lightroom Classic. When I click on any slider, its value immediately jumps to the far left, and the slider handle does not stay at the position of the mouse cursor. This happens with all sliders in all panels. As a result, I can't set precise values, as shown in this video: https://youtube.com/shorts/xzsw9RcSnSA

System information:
- Lightroom Classic: 15.6
- Mac: MacBook Pro 16-inch (Nov 2023)
- Chip: Apple M3 Max - Memory: 48 GB
- macOS: Tahoe 26.0.1
- Input device: Mouse only (no trackpad or drawing tablet in use)

What I observe:
- After clicking a slider, the value jumps to the far left instead of staying where I clicked
- The handle is not located under the mouse cursor
- This happens with all sliders
- The problem started about a month ago. It did not begin after an update to Lightroom or macOS, as I had not updated for some time before it started.

What I've tried (none of these helped):
- Tried several different mice, with the same result
- Turned off "Use Graphics Processor" in Preferences > Performance
- Reset Lightroom Classic preferences

as anyone experienced this, and is there a fix or workaround? Thank you!

I got the same bug, whenever I wanna click on the adjustment bar it sends me off to the far side of it making it extremely to work with.

Does adobe provide system requirements with its upgrades?  I don’t recall seeing them with the latest release of Lightroom Classic

Update MacOS to 26.7.1 (or macOS 27) and the problem will be solved.

I just updated to Lightroom Classic 15.6 Release: September 2026

I now have an issue on the Develop and Print Tabs where whenever I select a slider on the right hand side of the screen (i.e. in “Develop” - “Exposure”, “Contrast”, etc.) the slider automatically moves to the lowest value, and when trying to drag the slider, the mouse location is not on the eyedrop of the slider, rather is a distance to the right away from it.

I have tried disabling the GPU in preferences and have also restarted my machine with no change in the issue.  Has anyone experienced this issue and have they found a fix?

System:

• Mac Studio 2025 M4 Processor
• 128 GB
• Tahoe 26.3
• 8 TB Hard drive.

Thanks in advance.

 have an issue on light adjustment bar, while i try to click the spot using arrow the spot it self moving to begging of the adjustment line and i cant click it. 

You do not give information about your computer (always do that when you report a problem!), but I bet you use a Mac running MacOS Tahoe 26.3 or lower? If that bet is correct, then update MacOS to 26.7.1 and the problem will be over.

The sliders are not working accurately, for instance, If I want to set my exposure to -10, it goes all the way to -100.

Are you using MacOS Tahoe version 26.3 or lower? Then this is a known issue. Update MacOS to 26.7.1 and it should be solved.
