I have an application based on VTK 8.1.0 which only runs with OpenGL ES 3.0 Mesa 19.2.8 (Ubuntu 18). I want to run it in ubuntu 20 but the problem is that the version of opengl library is OpenGL ES 4.6 Mesa 20.0.4. Is there a way to run my application on ubuntu 20 with OpenGL ES 3.0 Mesa 19.2.8? I mean is possible make an upgrade of that libraries or run that application with a old version of opengl binaries?
Adicional information:
Example laptop on Ubuntu 18:
$ apt list -a libgl1-mesa-dri
