Lumetri color not updating changes in real time

I just installed the 25.2 and I noticed a big improvement too. It's not 100% responsive yet, but it's usable.

I was having the same issue on a M4 Pro, but updated to 25.2.0 and this seems to be improved.

My apologies, I responded in the wrong thread. 

Yes is does show an issue in 25.2 beta. Lumetri directly on clips will give a 15 second lag.

Same project in 25.1 no issue.

Does this also occur in the current 25.2 beta? We resolved an issue with Adjustment Layers that will hopefully address these issues. Sorry for the disruption.

I recently updated to the 2025 version, and suddenly I can't color grade on adjustment layers anymore. Previously, I could do that with no problem, but now in the 2025 version, it won't update on the clip in real time which is super annoying. Does anyone know why this is or if it is some setting I have to check or uncheck? Again, there was no problem doing this with older versions of Premiere, it's only now occurred on the newest version of the program.

I want to add that adjusting the color knobs directly on the clip works just fine, it's only when using an adjustment layer that it doesn't update in real-time and it gets laggy, so it has to be something with the adjustment layer.

It seems like there is a bug with adjustment layers since anything I throw on it, makes the timeline and project laggy.

Hi everyone, I'm a 12-year full-time professional in Premiere Pro and while I often read these community forums to leverage everyone's knowledge on fixing problems and bugs, this is my first time actually chiming in.

I noticed the Lumetri sliders lagging immediately after the 25.1 update in the project I was working on when the update happened. I didn't realize the adjustment layer above is actually causing the lag until reading these posts but I can absolutely replicate this issue every time on any clip that has an adjustment layer on a track above. If I turn off the video track the adjustment layer is sitting on, the sliders' effect immediately goes back to normal.

Do you have the problem with new projects on 25.x, or only projects you are updating?

At times a cleaner update to new major app versions is done by creating a new project file in the new version, then importing the assets of the older project file.

Any way you do it, when bringing a project into a newer version, dump the cache files on launch by holding Shift down while launching. Select dump all cache files.

I understand what you're saying but as long as everything works normally by rolling back to the previous version of Premiere Pro it means that there is no project corruption going on. It's simply something that Adobe messed up in this newer version that needs to be fixed. I open old projects all the time so this is annoying and I won't even be attempting to use it on new projects if the old ones will not behave as in previous versions of Premiere.

Trying with a new project would be useful and informative.

Also, sometimes with project or sequence corruptions, creating a new project, and using the MediaBrowser panel, you can select the old project, then import sequences from that project to the new one.

Doing that one at a time can at times show which work and where the problem is. So most of the project is then salvageable.
