NvFBC is unable to capture certain applications that bypasses the DWM compositor, for example, Firefox playing video in full screen. This has been a known issue for a long time with Nvidia's ShadowPlay, see: * https://www.nvidia.com/en-us/geforce/forums/geforce-experience/14/233709/ * https://crbug.com/609857 Nvidia won't fix this, but there are workarounds. For example, we create a transparent 1x1 layered window, which forces desktop composition to be enabled. Note that SetLayeredWindowAttributes also supports alpha-based transparency, but setting transparency to 0 will cause DWM to skip composition. We could use a transparency of 1, but this ruins the image by the slightest bit, which is unacceptable. Therefore, we must use chroma key-based transparency, which tricks DWM into compositing despite being fully transparent.
