Why export to Windows (virtualbox) turns image upside down but export to macOS works ok?

I’m using Godot 3.2.1 compiled from source, with ImageTools module (GitHub - Xrayez/godot-imagetools: [DEPRECATED] The module is available as a component of Goost.), on macOS where, both running from the IDE or from an export, works as intended, as shown.

However, when exported to Windows and run on a virtualbox 6.0.20 Windows 10 vm, the image turns upside down, as the next picture shows.

I’m using GLES2, and control nodes to automatic positioning the nodes (almost all nodes are control nodes). Since this is a tool just for me, to help me with my next game development, I’m not very worried, yet, I would like to know if this is a known bug, if anyone as this problem, if it is a virtualbox incompatibility issue, anything that might help me understand this. Thank you.

VirtualBox’s accelerated OpenGL implementation has many quirks. I would recommend using the slower but more accurate mesa-dist-win instead. (Remember to disable 3D acceleration in VirtualBox before installing it.)

So this is an issue with all software that uses OpenGL running on virtualbox? Not just Godot-made software?

Done some googling and found that it is a known virtualbox issue: #19237 (VBoxSVGA OpenGL upsidedown) – Oracle VM VirtualBox

So I guess it’s safer to assume that, software using OpenGL, in this case, made with Godot, do not run properly over virtualbox.
