Kdenlive crash report

SUMMARY
***
When OpenGL is activated and trying to open a video, Kdenlive crashes.
If I open a video with OpenGL disabled and save the project, then turn on openGL and load the saved project, everything works.
Without OpenGL, 4K60fps playback on Timeline is very slow.
The error occurs on Kdenlive 21.12.2 and older versions. I use openSUSE Tumbleweed and installed Kdenlive from the repositories, also tried the Flatpak version, but the result is the same.
It also doesn't matter if I'm using an Intel or NVIDIA GPU.
***


STEPS TO REPRODUCE
1. Enable OpenGL in playback settings
2. Open 4K60/50fps video


OBSERVED RESULT
kdenlive crashes

EXPECTED RESULT
Kdenlive won't crash
