3D mesh gets abnormal trembling on android devices powered by MediaTek Dimensity and Huawei Kirin processors. about godot HOT 7 OPEN

This is likely a precision issue in the mesh skinning shader, which could be alleviated by adding highp qualifiers in the right location (at a performance cost). I'm surprised this occurs on non-Qualcomm GPUs though; usually, it's the opposite.

Thanks, can you tell me more details on how to adding highp qualifiers in the right location ?

@dsyze In this file https://github.com/godotengine/godot/blob/master/drivers/gles3/shaders/skeleton.glsl You would replace all the places where it says mediump with highp. And then below, in the body of the shader, when a new variable is defined you would add highp as well (e.g. highp vec3 instead of just vec3)

Thank you, sir! I will try.

Unfortunately, the issue persists even after using the recompiled editor and the Android export template.

Could you share the updated version of the skeleton.glsl file you used so I can verify you changed all the necessary places?

Also, to confirm, you recompiled the editor and the android export template right?

Thanks a lot.
