Thanks for the extra information! I don't get notifications for and don't look at my reviews very often, so it's very easy for stuff to slip by me there.
I use Godot 3.4's GLES 3 renderer (which does have a GLES 2 fallback - you can launch it with --video-driver GLES2 to force that, though it doesn't look ideal), and I've had the game running on Intel HD-3000 chips in the past. It's Godot 4.x that doesn't have an OpenGL 2 renderer.
I'd love to see a copy of your game log if you're willing to share one. If not, please do let me know if you come up with a solution. There might be something I can do to help the situation, and I'd like to have a solid understanding of the problem so that I can help others in the future.
