(Win11) Lightroom Classic 12.2.1 crazy develop sliders

[Photos_by_Larsson]

LrC 12.2.1 on windows 11

Since last update, sliders are acting crazy. When I pull a slider in develop mode they seem to disconnect from the mouse/pen tool. I usually can slide the sliders back and forth with no trouble until I find the perfect level of black or shadow or whatever. But now the sliders reset themselves, or just don't react to my mouse/pen tool. This is whithout me letting go of the mouse button. Also I have testet a different mouse - same issue. It also happens when I use gradients in mask. And it also happens in camera raw.

Hope you can help with this somehow?

Kind regards

Lasse

Hey Lasse. Welcome to the Lightroom Community. I'll need more info to help you figure this out.

Would you mind recording your screen & share the video with us here? Are the sliders slow or jumpy?

Adjustment slides tend to change behavior with Windows's Shift/CTRL keys.

As a test, use the On-screen keyboard on Windows to check if the key press is being recorded as expected. Let me know how it goes.

Thanks!

PS: I liked the original title, but it must be adjusted.

What you can try first is to reset the preferences to the default settings.

Reset Procedure:

• Close Lightroom.
• Windows: Hold down [Alt]+[Shift] while restarting Lightroom.
  Mac: Hold down [Opt]+[Shift] while restarting Lightroom.
• Overwrite the Preferences when prompted by the dialog.
• Close Lightroom.
• Restart Lightroom.

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

If this doesn't help 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.
