No clients listed in intel_gpu_top

intel_gpu_top does not show any clients, although clients are definitely rendering (hardware-accelerated video).

The paste at the very end of this entry doesn't just cut off the clients, they are simply not present, regardless of the state of the runtime toggles (sort/display/aggregate).

To reproduce:

• sudo intel_gpu_top
• start any application which consumes resources tracked by intel_gpu_top

//exp: some information is rendered below the fancy graph rendition //act: only the graph rendition, no further details in the bottom section

System environment:

• Dell Inspiron 16 Plus (7610) with Nvidia RTX 3060 dGPU
• X11 / Xorg == reverse PRIME configuration, so Intel iGPU renders everything
• external screen on HDMI port attached to Intel output port (and no MUXing involved; the Nvidia dGPU is literally powered down, not involved at all - also validated via nvidia-smi)
• Fedora 36 (5.17.8-300.fc36.x86_64)
