Unity3d editor on Linux shows OpenGL 2.1 (Deprecated) in the title bar

The editor shows “OpenGL 2.1 (Deprecated)” in the title bar even though I should have OpenGL 4.3 installed.

Is it something to worry about?

Running glxinfo | grep version shows this:

server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
OpenGL core profile version string: 4.3.0 NVIDIA 361.45.11
OpenGL core profile shading language version string: 4.30 NVIDIA via     Cg compiler
OpenGL version string: 4.5.0 NVIDIA 361.45.11
OpenGL shading language version string: 4.50
