Issue description

when I add a shader to a spatial or 3D mesh the preview window sometimes become buggy and unresponsive . I think it sometimes also mess up the script's preview tho it's uncommon and harder to replicate

Steps to reproduce

@shahriarlabib000 Which Android device model are you using?

If you can't reproduce this in 4.2.x, I guess it's related to https://github.com/godotengine/godot/pull/83976 as you mentioned the mesh preview (which always uses 4× MSAA).

@Calinou not the mesh preview rather the actual viewport (sorry idk what its called like the main viewport that is the biggest and in the center that gets buggy and sometimes doesn't move in 3d space according to the on screen joystick movement or rather it moves but the viewport doesn't update) sorry idk what i was talking about

tested it on 4.3.beta3 I think only the camera view isn't update. everything else feels very smooth. and yes it definitely only happens when mesh preview appears as @Calinou said
