Lumetri takes about 15 seconds to update its edits in the Program monitor/scopes

Build 90 and earlier.

W11, gtx1070ti

source clips canon mxf intraframe.

preview codec Prores LT.

Playback in FULL is smooth.

 

It looks like I am not the only one:

Yep, have also been experiencing issues with lumetri colour where it will no longer update live. It's pretty bad on 25.0 on large timelines as well

 

Here is a screen recording of 25.0 on a rather large timeline, note; I am moving the mouse the entire time but it does not update until I let go. This is all footage proxied to prores - Moving to a smaller timeline does NOT change this behaviour for me. It happens regardless

If there are just a few clips in the timeline Premiere performs like expected.

Adding more clips, the lag increase with the adding of the clips.

Timeline is 18 minutes.

 

Importing same project into 25.1 there is no issue.
