OpenGL in Linux guest OS when hosted on Mac

I have written an application in Unity that I would like to test on Linux using Parallels on Mac. I installed Mint but when I tried to run the app it fails, being unable to locate the OpenGL libraries.

I did find this in the Knowledge Base from 2018 that indicates there is no OpenGL support in macOS and Linux virtual machines: https://kb.parallels.com/124138

Can anyone confirm if this is still true?

 

OpenGL 1.3 seems to work fine, however 1.4 is a bummer -- there is a bug inside libEGL provided by Parallels:

Code:

OK, I worded it poorly, I am afraid. Parallels Desktop supports OpenGL 2.1 inside Linux guests (in comparison to OpenGL 3.* for Windows guests). It crashes when it comes to EGL 1.4. All in all, it seems to be related to poor development support for the Linux guest tools and libraries and unwillingness to open source the guest stuff to get it moving, I think. In other words, the company does not really care about Linux share of their customer base, hence does not allocate any resources to develop in that area.

 

Also, Parallels claims that they support OpenGL 3.3 for Linux guests here -- https://download.parallels.com/desktop/v16/docs/en.lproj/43132.htm -- I never seen anybody being able to achieve that yet on their systems, though.

 

Lovely, thanks.

 

Parallels 19 supports OpenGL 4 on Ubuntu 22.04 guest:

OpenGL version string: 4.0 (Compatibility Profile) Mesa 23.0.4-0ubuntu1~22.04.1

My OpenGL 3.3 app is running though the framebuffer claims to be sRGB but, even with GL_FRAMEBUFFER_SRGB enabled, the fragment shader outputs are not being encoded to sRGB.
