Mesa 3D graphics
Ao longo dos anos, o projeto cresceu para implementar mais APIs gráficas, incluindo OpenGL ES (versões 1, 2, 3), OpenCL, OpenMAX, VDPAU, VA API, XvMC e Vulkan.
Uma variedade de drivers de dispositivo permite que as bibliotecas Mesa sejam usadas em muitos ambientes diferentes, desde emulação de software até aceleração de hardware completa para GPUs modernas.
Mesa se conecta a vários outros projetos de código aberto: a Direct Rendering Infrastructure e X.org para fornecer suporte OpenGL no Linux, FreeBSD e outros sistemas operacionais.
Mesa 20.2.X
Mesa 20.2.0 implementa a API OpenGL 4.6, mas a versão relatada por glGetString (GL_VERSION) ou glGetIntegerv (GL_MAJOR_VERSION) / glGetIntegerv (GL_MINOR_VERSION) depende do driver em particular sendo usado. Alguns drivers não oferecem suporte a todos os recursos exigidos no OpenGL 4.6. OpenGL 4.6 só está disponível se solicitado na criação do contexto. Os contextos de compatibilidade podem relatar uma versão inferior dependendo de cada driver.
O Mesa 20.2.0 implementa a API Vulkan 1.2, mas a versão relatada pela propriedade apiVersion da estrutura VkPhysicalDeviceProperties depende do driver específico sendo usado.

- TGL B0 Stepping gpu hangs on many dEQP-VK.subgroups.quad nonconst tests
- [spirv-fuzz] Shader generates a wrong image
Opinião
Atualmante para quem utiliza placas de vídeo Intel e AMD é totalmente dispensavel o uso de drivers proprietários.
Mesmo para hardware antigos e modestos o Mesa propicia um uso super satisfatório mesmo em ambientes graficos com mais recursos graficos.
Instalação
Para manter o Mesa sempre atualizado, mantenha o seu sistema operacional atualizado.
No caso do Ubuntu você pode seguir a matéria abaixo para ter sempre a ultima versão do Mesa.
Dar uma turbinada no Ubuntu e derivados com Mesa Driver para Intel e AMD
No Debian se você é usuário do Testing pode tornar ele híbrido e utilizar o Mesa do unstable.
