Question

Random periods of high contrast appear Pr 25.5 - 26 , Win 11

This happens both while working on the timeline and after rendering, RANDOMLY, and greatly interferes with color correction. It started after upgrading to Windows 11, followed by the release of Premiere 25.5, and all the trouble began. The image may flicker in contrast.

All my drivers are up to date, and I installed the Studio driver via the N app and Intel GS.

I found a similar thread on Reddit that explained that the problem could be caused by the RTX5090 and UHD Graphic 770 (13900k) rendering in different color spaces.
Random periods of high contrast appear.

To see an example of a render of this kind, watch the first 1-2 minutes of this video: https://youtu.be/Cg4xQBXNSFE

How can I fix or unify the color spaces?

    I noticed that it happens when you add graphics, such as the thumb up at 18 seconds. I would try to select the timeline and then go to Sequence > Sequence Settings and then un-check Composite in Linear Color and click OK.

    This usually solves issues like this.

    Are the video and graphics in the same color space?

    I don't use graphics in my wedding videos; it's unnecessary; the problem lies in decoding in different color spaces.

    I shoot in the 265 codec, and this codec hasn't been fully optimized in the program yet.

    How many different color spaces do you work with, at the same time on the timeline?
