Mac Mini Flickering Lightroom Classic

[Patrick Justin]

I'm having an intermittent issue that causes my Lightroom Classic image preview to flicker when I move my cursor between the develop tools area and the image window. Also when I make an adjustment it's very clunky. 

When I go into lightroom preferences and I switch graphics processing to off then it resolves the issue (and subsequently if I move it back to on it also stays fixed until I continue using it then it starts again)

I would prefer to keep using graphics processing as the adjustments to the image are very smooth however when turned off is very clunky. 

I've attached a screenrecord below of the issue. 

Hopefully someone can help.

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.

Hi Axel,

Thanks for taking the time to reply. In my initial post I mentioned that I had already turned the graphics processing off as per your recommendation however this results in a reduced performance. When graphics processing is off then sliding the exposure bar (for example) doesn't result in a smooth transition but rather a clunky stepped transition. While it does fix the initial flickering problem it still isn't a great experience. 

I'll try reset the preferences however and see if that helps. 

Best,

Patrick

You're using a computer that needs to run in emulation mode (Rosetta 2) in order that it can even run Lightroom Classic. So, anomolies such as you are experiencing are to be expected.
