As of right now, enve requires OpenGL 3.3. The error message should probably point to that, as it could be a common problem.

enve requires OpenGL 3.3.

Does it happen because enve require OpenGL 3.3 for blending modes? Could it be solved in any way?

As I know Olive app has special mode ($ ./Olive*.AppImage --disable-blend-modes) especially for running on older GPU

I will look into this.

I am afraid it cannot be done. The oldest OpenGL version enve (maybe) could support is 3.0. Enve relies on many newer OpenGL features ex. Vertex Array Objects, Framebuffer Objects.
