Flickering images in Lightroom

[#1]

Hi everyone

I am nearing the end of my patience. I have serious issues on a Dell XPS 15 laptop with double graphics cards. The powerful one, which is causing the problems, is the Nvidia GeForce GTX 1650 Ti, which should be the latest and greatest they provide.

I have visible flickering in Lightroom (see the attached video) when adjusting an image and the background in Photoshop also changes brightness when working on an image.

I have spent hours going through all the troubleshooting links I could find, so please don't send me any more of those. I want to know if this is fixable or if I should just pray for a Lightroom update that takes care of it. All my drivers are up to date, and even uninstalling them and reinstalling them hasn't changed a thing.

Any help is welcome, I am a photographer and I really need this fixed

Which CPU do you have in your XPS15?

Which screen resolution do you have?

Just to test, is the flickering still there if you deactivate GPU support in LR?

[#4]

Hi, I have an Intel i7-10750H @2.60GHz, my screen resolution is 1920x1200 pixels and yes, the issue disappears if I separate Lightroom from the Nvidia GPU

Cannot view your attached file.

I will ask a silly question. Did you make sure the cables between GPU and monitors are properly attached, not loose?

The powerful one, which is causing the problems, is the Nvidia GeForce GTX 1650 Ti

So, two GPU cards? And not the same? LrC can have issues with non identical GPU cards

Something to do with conflicting drivers

Hi, I'm on a laptop so I don't have an external screen. I am familiar with the link you sent me but all of those steps haven't solved my problem. I am not a tech expert and have just recently switched to Windows, but yes as far as I understand I have two GPUs, an Intel UGD Graphics and the Nvidia one. I have tried updating the drivers, then I have even uninstalled them and reinstalled them, all to no avail...

Mixed Integrated Video control, and Descreate GPU should not be a problem.

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.
