Possibly Linux/Nvidia specific, has been that way since at least 2014, and without proof even before. Reported because of conversation in T1702.

Archived graphcisinfo.txt from 2014-09-15, for comparison:
Running on thread: ClientThread Adapter: null Driver Version: null Vendor: NVIDIA Corporation OpenGL Version: 4.4.0 NVIDIA 343.13 Renderer: GeForce GTX 560 Ti/PCIe/SSE2 GLSL Ver: 4.40 NVIDIA via Cg compiler
In both cases, the driver version is identified correctly in the "OpenGL Version", and the graphics card in the "Renderer" item.
Tested:
"Adapter" shows "null"
"Driver Version" shows "null"
Expected:
"Adapter" shows graphics card name/bus/bus ID/capabilites, eg. "NVIDIA GeForce GTX 960/PCIe/01:00.0/SSE2"
"Driver Version" shows kernel module version, eg. "NVIDIA x86_64 367.35"
