Question

External Monitor Suddenly Lagging in Premiere Pro Only

I have just upgraded to Monterey 12.2.1 on my M1 Max 16inch Macbook Pro.

My Premiere is version 22.2.

Ever since I upgraded my Monterey to 12.2.0 (and still not fixed on 12.2.1) my external LG monitor has been causing lag in Premiere. The lag only occurs when I change the size of the workspaces, or if I click on the different work spaces. There is absolutely no lag when scrubbing through the timeline or playing a clip.

As soon as I unplug my external monitor everything works perfectly smoothly.

I've attached a screen recording to show what is happening. The wide video is the external monitor.

Has anyone experienced anything like this?

    UPDATE

    Not sure if this was what fixed it, as I stopped using my monitor for awhile, but my housemate got a new curbed monitor and I wanted to test it so I plugged my Macbook in, and it worked perfectly smoothly. I then plugged my old monitor in and everything was working perfectly fine too. No idea what changed but has anyone tried another monitor and then gone back and it's worked?

      Thanks for the update.

      Data communication channels can sometimes get messed up. HDMI is particularly bad. But DisplayPort and VGA can sometimes go South on ya as well. Disconnecting and re-connecting the monitor is always worth a check.

      Glad it's working for you!

      Originally I did disconnect and re-connect the monitor multiple times, even trying a few days later and restarting my Macbook. I'm not sure if using a different external monitor reset something?

      So, I used a slight variation of @minutephysics's because I don't have the "Use Rosetta" as an option from Get Info... but I did set my displays to mirror, "Run (Intel)" through the Creative Cloud app, ran it, closed it, stopped mirroring, opened the not-Intel one (confirmed via Activity Monitor) and a project that I was having the delay on, and it worked properly! I restarted and it's still good, so hopefully it remains so!

       

      When I opened the Intel one, I got a progress bar that ran through a bunch of plug-ins or something, which I've never seen it do on the M1 version, so I'm wondering if that has something to do with it. Dunno what exactly it would be, but I'm happy it seems to be working now.

        No solution, just here to say I have been having this same exact issue with my M1 Max 16' Macbook Pro and my LG 5k Ultrafine Display. Only happens with premire and makes it almost unusable. Hoping for a formal solution soon.

          I also have had the same issue: laggy/slow UI in Premiere on external monitor with brand new 16" M1Max, no performance issues with the external monitor in any other apps.

           

          I appear to have a solution: at least, the below has fixed the problem for me (perhaps only temporarily? I'll report back).

          1. I quit Premiere

          2. I mirrored the displays (rather than extending).

          3. I changed Premiere to open with Rosetta using the "get info" window on the app (it took a long time to open, presumably as something downloaded for Rosetta).

          4. Then I ran premiere, and it works fine.

          5. Last, I quit Premiere, turned off mirroring, turned off "use rosetta," reopened Premiere, and the issue seems solved.

           

          Based on this, I speculate that something in the M1 version of Premiere requires something from Rosetta to work, and running PP with Rosetta just once at least gets that set up? But this is pure speculation. I'll report back with updates and will be eager to hear if this works for anyone else - especially if you just try Rosetta rather than the screen mirroring part of the solution.

            That's a clever solution! I hope it turns out to be the right one. 

            Can I call you to troubleshoot my car next time it acts up? 😀 😀 😀

            Ha.

             

            Also I can report that the issue appears to remain fixed after restarting the computer.

            I've recently got my 16" M1 Max 64gb and again i'm having the same issues as everyone here. I just got the Apple Studio Display and premiere is noticably laggy, when I unplug the monitor it goes back to normal. Monitor is fine with other applications it just seems to be premiere.

              Same as everyone else. Finally hooked my 14" with M1 Max to my pair of external monitors and every action in Premiere (and only Premiere) has a .5- to 2-second lag and gosh it's so frustrating. I get the delay when using both the trackpad and my external mouse.

                Are the people with lagging issues running Pr under Rosetta or the native Apple silicon version?

                I wonder if there is a conflict/delay in processing between M1 graphics and Intel Pr?

                Speaking for myself only;

                 

                Under the "Get Info" window for Premiere Pro the tick box for "Open using Roestta" is UNCHECKED, however in the creative cloud app when I click the 3 dot menu it says "Open (Intel)"

                 

                On Adobe's official list of M1 supported apps, Premiere Pro is there, but I do wonder if that includes M1 Pro and M1 Max as those seem to be the chips having the problems.

                 

                Tried Premiere Pro Beta under the "Beta Apps" in Creative Cloud and it was just as bad if not worse.

                I was thrown off by the "Open (Intel)" thing at first, but I think that is actually just giving you the option to open the Intel version. If you click on that, it will open the Intel version, if not, then it opens the "Universal" (M1-compatible) version.

                 

                I posted in this thread earlier and will just give an update that I'm no longer having the issue, but didn't do anything specific to fix it!

                I'm having similar issues with my 16 inch MacBook Pro. Mine isn't limited to just workspaces however, I can't even scrub through the timeline or click on anything without a full 1s-2s delay. Can also confirm it does this on an Asus P278QV so I don't think it's specific to any monitor in particular.

                 

                As stated, when on the built in display everything runs perfectly smooth. 

                 

                Bumping for a solution

                  Wow, I have also just started having the exact same issue on my 14" MBP with M1 Pro.

                    No solution; data point only:

                    I am running a 16" 2019 MBP connected via a docking station to an external Dell 4K monitor.

                    Big Sur 11.6.4

                    Pr 2022.2.0 (Build 128)

                     

                    No lag issues at all.

                    As I said I didn't have any lag issues before I updated my OSX.

                    My M1 Max and old 16inch 2019 had no problems before this.
