Playback Issues in Color Tab

Hi there

I'm having playback issues on Resolve with grades on singel nodes and e.g. stabilized clips - this is something I've never experienced before. I'm on the same machine using the same material as before. Though it's just in the color tab which is odd. In the edit tab it's smooth.

I'm on Resolve 15.2.4 on a Windows 10 machine: Version 1803, OS Build 17134.590



Anybody experiencing the same or has a clue what this could be about?

Cheers

I just figured: It's only in the UI viewer...when I use the BDM Card for monitoring; there it's fine. Anybody had this problem before?

Updated to 15.3 - the problem remains ins the color mode UI: stuttery playback...also the playhead is stuttering.

Anybody an idea what this is about?

Cheers

This can occur when you have certain options activated in the viewer, like Power Window for instance. Does it improve if you set it to Off (the dropdown menu at the bottom left of the viewer)?

Before v16, when the scopes weren't GPU accelerated, you would also get severe UI slowdown when the monitoring was set to 4:4:4 and "Video" data levels.

That was it. Thanks for the solution.
