Lumetri Color not working

[Infinite Productions]

For some reason my current project file is acting up. The lumtri colour tab is suddenly very unresponsive. Even in the basic tab I click and hold the slider to move and it does nothing on the tab but still makes adjustments on the actual footage, all sliders remain at zero and takes ages to switch between panels. Playback is fine. Anyone else had this issue?

Have done an uninstall and clean reinstall.

Deleted cache and preferences and restarted.

Created new project files and sequences and copied footage in but same problem.

Have opened the project while another project is open, then closed prior project and still happens.

Sometimes I do need to click through another panel and back onto the clip in the timeline. Or jump to another sequence & back. But it quickly gets back to normal. Huh.

Most likely this is an issue caused by nested audio.

To test: copy timeline deleted all nested audio and test lumetri.

Spot on, working as normal again now. What a strange glitch. Thank you very much!

Thank you! This was exactly my problem too.

This problem is very frustrating. 

I added the "fx" button and toggled it and that helped to some degree with Lumetri Color.

 The video's still preview in a lower resolution when not played.

The video resolution choices between playback & pause are in the Program monitor panel. You can either right-click the monitor or click on the Wrench menu icon and set playback resolution separately for paused and playback.

Another option is High Quality Playback.
