--- Comment #10 from balooii <balo...@proton.me> ---
The provided logs suggest that there may be a problem with detecting OpenGL as
vendor and renderer are reported as empty "". It should print something about
Nvidia if that is the GPU you're using.
```
OpenGL vendor ""
OpenGL renderer ""
OpenGL threaded? false
OpenGL ES? true
OpenGL maximum texture size = 3801209
OpenGL maximum viewport size = 271384704 x 32766
QOpenGLShaderProgram: could not create shader program
QOpenGLShader: could not create shader
```
I would suggest to
* check that your nvidia drivers are up-to-date, as well as the flatpak GL
runtime. The runtime should be called like this
`org.freedesktop.Platform.GL.nvidia-<MAJORVERSION>-<MINORVERSION>`.
* try to start the app via appimage instead of flatpak
* try accessing OpenGL info about your system without using Kdenlive e.g. by
running command `glxinfo -B`. This should also show vendor/renderer
information.
* if it still cant detect your GPU as openGL renderer, try starting the app
with these environment variables set QT_QUICK_BACKEND=software
QT_OPENGL=software
