Not really, but it would probably be useful to state your video driver
(AMD, Nvidia proprietary, Intel, Nvidia free etc.) and display server
(X11, Wayland), e.g. for me:

$ inxi -G
  Device-1: Intel IvyBridge GT2 [HD Graphics 4000] driver: i915 v: kernel
  Device-2: NVIDIA GP107 [GeForce GTX 1050] driver: nvidia v: 515.65.01
  Display: x11 server: X.Org v: 1.20.14 with: Xwayland v: 22.1.3 driver: X:
    loaded: modesetting,nouveau,nvidia unloaded: fbdev,vesa gpu: i915
    resolution: 1920x1080~60Hz
  OpenGL: renderer: Mesa Intel HD Graphics 4000 (IVB GT2) v: 4.2 Mesa
