I'm using a vm so this might be the problem

This is a known issue with Lavapipe in Forward+/Mobile, which I can reproduce on Linux. It does not occur with llvmpipe when using the Compatibility rendering method.

It's likely an issue that should be fixed in upstream Lavapipe, as I don't think we are doing anything against the Vulkan specification when rendering the 3D editor grid.

VMs don't have Vulkan hardware acceleration available (and OpenGL support is often limited to OpenGL 2.x), so you should run Godot on bare metal whenever possible (or use VFIO passthrough). It'll also be much faster.
