Premiere Pro UI is lagging!

[Arthur5FBC]

Hey!

So I have a three-monitor setup with most of the panels open on each screen, but I am getting loads of lag from the UI.

The playback is fine, running smoothly and everything, but the UI lags when I move things around; the playback head jumps. When I switch it back to one monitor, it is fine. This only happens when I have extra panels on different monitors.

This always happens, no matter what footage I am editing or how big the project is.

Specs:

NVIDIA GeForce RTX 3090,

AMD Ryzen 9 3950X 16-Core Processor,

64GB (3200) RAM.

Does anyone know why this is happening?

Are you using the latest Studio Driver?

[Arthur5FBC]

Yep have the latest version of everything

What's weird is it only happen with certain panel, such as the effects panel, the audio panels and lumetric colours

If that doesn't work, try resetting the Workspaces:

If that doesn't work, try Preferences > Audio Hardware and set Input to None.

If that doesn't work, try creating a new project and import the old one into it.
