Code:

Extended renderer info (GLX_MESA_query_renderer):    Vendor: Mesa (0xffffffff)    Device: llvmpipe (LLVM 15.0.6, 128 bits) (0xffffffff)    Version: 23.2.1    Accelerated: no    Video memory: 3792MB    Unified memory: yes    Preferred profile: core (0x1)    Max core profile version: 4.5    Max compat profile version: 4.5    Max GLES1 profile version: 1.1    Max GLES[23] profile version: 3.2
When you run the same program locally, the accelerated OpenGL only supports 3.1...

Code:

Extended renderer info (GLX_MESA_query_renderer):    Vendor: Broadcom (0x14e4)    Device: V3D 4.2 (0xffffffff)    Version: 23.2.1    Accelerated: yes    Video memory: 3792MB    Unified memory: yes    Preferred profile: core (0x1)    Max core profile version: 3.1    Max compat profile version: 3.1    Max GLES1 profile version: 1.1    Max GLES[23] profile version: 3.1
