Why is vulkan slowing down on android?

Godot Version

4.7 dev.4

Question

I have poco x 7 pro, and the use of rendering “Mobile”, I’m faced with the fact that this rendering mode slows down. The idea is to use a Vulkan it should be much faster than OpenGL, But in this situation, it’s quite the opposite. Is that really the mode “Mobile” is it still not optimized, or am I doing something wrong?

@tibaverus might know.

What version of the Android OS is on your phone?
