Color Grades Flickering 18.6.3

The dev team sees the issue, and is investigating.

Any updates on this ? I left the files you requested out there.

It is strange. Hi Terry, are you sure you have installed latest Davinci from official blackmagic website, not from another?

Yes, I get the file directly from Davinci Resolve pop up.

Thanks for the dra. I see the issue on a couple different Windows systems and on an M1 Pro MBP with Resolve 19.1. Haven't regression tested to see if it's 19.1 specific or if it also happens with 19.0.3.

And I see the issue goes away when the Contrast node is bypassed.

I've asked the dev team to take a look. Please leave that .dra link active for a few days, if possible.

Can someone please assist with this, I have basically lost the ability to use Contrast in my Color Grades.

Do you have performance on in settings?

I have it set to automatic. Although, the issue occurs in the final render. I don't see the flickering in playback on the project.

Can you disable it? I'm fishing in seeing if the issue is in generating the frames or saving it to drive

I download Resolve 19.1.3 and I am still experiencing this flickering issue when using Contrast.

can i PLEASE have some assistance, I am unable to use contrast in my projects due to this !

Hello everyone. I agree with you that the problem exists. I have been experiencing flickering in the timeline playback and rendering results, which makes it difficult for me to use the color grade page. I have spent a lot of time trying to understand what is causing this issue. I have tried reinstalling drivers, installing new Linux versions, and changing various settings, but I have not been able to fix the flickering.

My current setup is:
OS: Linux
CPU: AMD Ryzen 9 5900XT
Memory: 128 Gb
Graphics: Nvidia RTX 4060

To try and determine which version of the software was causing the problem, I decided to install different versions and see if the issue persisted. Here are the results:
18.6.2 - no problem, this version works correctly

19.1.3 - flickering

I would like to share some advice for users who are experiencing this issue. Using version 18.6.2 has fixed the problem for me. I also hope that developers can investigate this issue further. I have attached logs and a video through Google Drive.

I don't know how to attach links to video. Forum doesn't allow me to public urls.

Edit

I also included links to videos (Google Drive) for each version:

18.6.6: https://drive.google.com/file/d/1my0ZjW ... ltviO/view

New forum users are not allowed to post URLs.

Just put a space near the front of the URL, so the forum system doesn't see it as a URL.

I don't see anything obvious in the logs. Seeing the issue could be helpful.

Dwaine - looks like you posted a response destined for a different thread?

Thanks Steve. Indeed that appears to be the case.

@Terry: I pinged the dev team about this on the 21st and they were going to get back to me. When I get a response, I'll pass it along.

Any updates ?

I can confirm this. On fedora system,
18.6.2 no flickering
18.6.6 flickers
19.1.3 flickers

It is a resolve issue. Nothing to do with hardware or OS.
And color grade using fusion color corrector works fine. This issue is limited to color nodes in color page.

I've tried 19.1.4 version, there is the same issue. Does anybody try 20 beta version?

Hello *

I also have this issue on my Nvidia 3050Ti 4GB Linux.
Currently 18.6.2 is the version I use even though 20 is in Beta and is about to come out.

Please Black Magic, fix this bug!
You could already reproduce the bug. What is holding you to fix it so your customers (people who bought Studio version) are happy using your product?
