Double Selection Bug in Lumetri Color RGB Curves

[Edit Videos]

Good day Adobe Community,

I keep running into this selection bug when accessing RBG curves in the Lumetri Color panel in any project I open up and work on. I do have the latest updates.

This bug appears to be two-part. The first part will not allow the RGB channels to be selected. Once I can kick this part of the bug an able to select channels, then the pointer will not appear to make changes (whether to pen or curve changing pointer).

I do all kinds of things to kick out of this double bug, including but not unlimited to:

- Close and reopen the Lumetri Color panel

- Twirl up and down

- Move the playhead back and forth over the clip so Premiere Pro can figure out what clip is being targeted

- Twirl around 'n' around somewhere else

- Etc. etc.

What generally works, as a last resort, is saving and closing the project, then reopening the project.

To say another way, I have the correct channel selected (once I get passed the channel selection bug) and when hovering over the channel point, the pointer will not change, but staying at the default mouse icon.

The bug is very repeatable and has been going on for at least several months.

I am 99.99% certain this bug has nothing to do with render times, because I can let the editor set there for a while, and the bug won't kick.

Also, whether working with shorter, longer, or upscale source clips, this same bug occurs. Most of our clips are either generic h.264, Topaz h.264 in .mov container, Nvidia h.264, ProRes, etc. Even with proxies, this same bug occurs.

It's as if the editor has difficulty figuring out which clip is being selected. No other functions in Lumetri Color panel seem to have this issue, just RBG Curves.

Thank you for any help in the matter.

Update: A video has recently been recorded to show what happens with this bug. When you see me hover over the channels, I am clicking to activate that channels, or at least attempting to. As I twirl around and away from curves, evently, I break out of the first layer of the, then not, then break out of the first layer again, and evently break out of the bug completely, where the mouse point can now select the channel can the pointer either turns into a pen or movement of the curve.

Hi @Edit Videos -  Thanks for submitting your bug report. We need a few more details to try to help with the issue.
Please see, How do I write a bug report?

What are your computer specs and version of Premiere Pro?

Sorry for the frustration.

Please let me know if there is anything else.


Warm regards,

Hi @Edit Videos - Can you let us know the driver version you are using.  Are you working on Lumetri color on the media file or an adjustment layer?  Are you saying you can't select the White, red, green, or blue icons?

Hello Jamie Clarke,

Thank you for the response.

For the original post, I recently added a video example. This even occured with the most recent Nvidia Studio Driver 572.60 for the A4000, just released about 24 hours ago. And the bug still occurs, as demonstrated in the video. I am working on the clip level with the supplied default Lumetri Color for each clip (not an adjustment layer or additional Lumetri Color in Effects Control).

As you see me hover over the channels in the video, I am clicking the mouse to attempt to select each channel. When you see me hover over the curves themselves (specifically the one that is already selected), the mouse pointer is not selecting and changing and I cannot effect the curve, whether moving it or the pen icon not showing up. Evenuatly I break out of the issue, but it takes some going here and there to make it work. I was able to do that without leaving the panel, because all I was recording was just the panel.

Hi @Edit Videos - That is very strange.  I can't reproduce this on version 25.1.  Are you using two external monitors?

Can you try and hold down "SHIFT" while launching Premiere and check the boxes
"Reset app preferences" (Backup Preferences first)
"Reset plugin loading cache"

Hello Jamie Clarke,

Yes, we use dual monitors, but I mainly edit on the extra wide Dell monitor. I generally do not have to split panels between monitors since the main monitor has a lot of width.

I started Premiere Pro holding down the shift key, checked the two boxes, and the editor started fine. I went back into lumetri color and so far the bug did not activate. Only time will tell.
