Hi, I have an annoying problem. When I hover with the mouse over a picture in develop mode the picture becomes slightly brighter. However, sometimes it gets darker. This also affects the background (grey in my case). Only restarting LrC helps.

 

Aynone knows what the problem is?

Try disabling GPU in preferences, any difference?

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Past that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

Thx for your answers, I appreaciate it. Indeed, disabling GPU acceleration seems to solve the issue (LrC-->preferences-->performance-->Use Graphics Processor "Off"). I'm using a MBP 2015 15" without dedicated graphics. So it might be the setting caused the problem then because there is no dedicated card to address?

If your MacBook Pro doens't have a dedicated video processor, then best you switch off GPU as it will reduce rather than improve performance.

Just to clarify: this bug occurs on Macbooks with dedicated graphics as well. I'm using a 16" 2019 model and I have the same issue like back then. The workaround it to switch off graphics processor for a second. You can switch it on immediately again if you like, it will work normally then.

Thanks very much for posting this. I started having this issue whilst using a second monitor with Lightroom Classic.

After extensive phone calls with NEC who made the monitor, Apple and Adobe - the issue was unresolved for a year.

Last night, found this post and it worked. Thanks so much!

By the way, you can turn it off and on again immediately, it will continue to work normally again until next time. For example after your computer comes back from sleep. But anyway, least annoying way is of course to leave the acceleration shut off.

Seeing this in LrC 11.2 on an M1 Pro MBP 14", when using an external monitor.

The workaround shown here does work.

This is a pretty bad bug, I would say - given that a lot of people will be using LrC on an external monitor. Any updates on when this will be addressed?

It doesn't matter if it's the laptop screen or the second monitor. It flickers when hovering and that disrupts the brain processing the info trying to colour correct. This clearly is a bug and needs to be addressed. Very annoying.

I am working with dual displays on Mac, no such issue. So yeah, there is a bug somewhere, but don't assume it's solely Adobes and not the GPU or something else.

Seeing this issue on my 2021 M1 Macbook Pro 16".

Also had the issue on my 2015 Macbook Pro with standard graphics 15"

 

This is a bug that makes editing very unreliable. Disabling the graphics acceleration is not an acceptable solution.

But does disabling GPU change the behavior; yes or no?

I do not see a solution to this super annoying problem, one I have been having, listed here. I am running LRC on a MacBook Pro M1 chipset and it is happening within that environment. Am I missing the elusive obvious here - what shows as the correct answer does not seem like a solution, just part of trying to do a differential diagnosis if you like. ANy thoughts Adobe folks?

LATEST

If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it. On the Mac, that's part of the OS update(s) so if this is the latest OS version, you may need to roll back a release.
