   if you can try this, it fixes the issue for me:
   #126

   (if you have newer unity version, or urp, let me know which one, if that code doesn't work there)

   unity confirmed this as a bug also,
   https://issuetracker.unity3d.com/issues/graphics-dot-drawproceduralnow-from-onrenderobject-breaks-when-worldspace-canvas-is-in-cameras-view

   and gave one workaround:
   "I have noticed that creating a new Universal RP project and reimporting your Assets folder makes the drawing render as intended."

   unity added more info, that its by design:

   After a further resolution with developers, we have decided that this issue is By Design due to the following reasons:
   The procedural geometry is being rendered after the UI panel so it is using the UI panel's transform, which is by design. The docs for https://docs.unity3d.com/2019.1/Documentation/ScriptReference/Graphics.DrawProceduralNow.html explain "Note that this call executes immediately, similar to Graphics.DrawMeshNow. It uses the currently set render target, transformation matrices and shader pass".

   https://docs.unity3d.com/ScriptReference/Graphics.DrawProcedural.html or https://docs.unity3d.com/ScriptReference/Rendering.CommandBuffer.DrawProcedural.html may be more suitable for this use case.
