Kdenlive 23.04.0. Video first frame is lighter than other frames

This version has a problem that previous versions did not have.
The first frame of the video added to the timeline is lighter than the other frames. It’s as if the other frames were filtered, but I didn’t apply any filters. Colors are darker. This occurs on all added videos.
Same result when the project is rendered.

System: . ASUS FX502VE Notebook. Windows 11 x64
Processor: Intel i5-7300HQ CPU 2.5 GHz
Video Card1: Intel HD Graphics 630
Video Card2: 4GB NVIDIA GeForce GTX 1050 Ti

That’s interesting!

Please log a bug report for this in https://bugs.kde.org and include this screenshot gif. Thanks!

Could not reproduce that in Linux with V. 23.04.0 (appimage).
Opened a new sequence (timeline) and added 2 clips as you describe.
No such problems, stepped through frame by frame.
A problem specific to Windows?

I think I found the cause of the problem. If render full color range is selected in the Rendering window, the first frame of the clips will be darker. Different video clips attached to each other in the timeline had the same problem with the first frame at the junction point (like the transition effect).

These problems do not occur when render full color range is not selected in the Rendering window.
