Hello! I have a laptop with switchable graphics (Radeon 780M + RTX 3050) and connected via USB-C Dock (HP Universal USB-C Dock) to DisplayPort Monitor (Lenovo 27inch). 

When I play a video - there is no hardware decoding process therefore CPU running on 50%. I opened about:support - and checked Codec Support Information - all codecs are software decoded only.
Then I checked recognized graphics adapters - 
```
"adapterDescription": "DisplayLink USB Device",
   "adapterVendorID": "0x000b",
   "adapterDeviceID": "0x000b",
   "adapterSubsysID": "0000000b",
   "adapterRAM": 0,
   "adapterDrivers": "Unknown",
   "driverVendor": "",
   "driverVersion": "",
   "driverDate": "",
   "adapterDescription2": "NVIDIA GeForce RTX 3050 Laptop GPU",
   "adapterVendorID2": "0x10de",
   "adapterDeviceID2": "0x25e2",
   "adapterSubsysID2": "3b1217aa",
   "adapterRAM2": 4096,

``` And viola - there is no integrated graphics adapter. seems like a Firefox doesn't know about it behind USB-C Dock.
