Been a while since I posted this issue and I tried some different things. I verified that the VDPAU is working. all drivers etc. are installed, verified the drirc file is correct and even tried out Shadowcker. In Shadowcker I get the same problem. I also wanted to try out the Shadow Live OS with NixOS but sadly I didn't get my PC to boot from the USB Stick with this Image. PC Immediately turned off after selecting the USB Stick with Shadow LiveOS as One-Time Boot Device. Nevertheless I can reproduce the Black Screen with the AppImage and the Docker Image. Especially with the Docker-Image this seems kind of strange. Researching the Internet I found some different directions. Maybe the mesa-driver Version is not working with the AppImage, even found some comments that cinnamon as the Window Manager isn't working with some Applications and the vdpau. |

Update on this: Used the official amdgpu "all-free" Drivers from the AMD Website. Now Hardwaredecoding is working properly libva info: VA-API version 1.7.0 Driver-Version changed from 20.2.6 to 20.1.6 after installing the packages. |

Hi guys ! I can confirm this is due to Mesa drivers 20.2.6. However video hardware acceleration is still working in Google Chrome. The issue occurs on Ubuntu 20.04.2+ as well https://forum.shadow.tech/technical-assistance-7/ubuntu-20-04-update-to-linux-kernel-5-8-broke-hardware-video-decoding-2058 |

@Klauerstoff can you link the drivers you used ? |

Problem also occurs with Mesa 21+ |

Had some Problems with my System running official AMDGPU Drivers version 20.45 and Kernel 5.8. Upgraded to version 20.50 yesterday. Kernel Problems are fixed and shadow app is still working with hardware decoding. https://www.amd.com/en/support/kb/release-notes/rn-amdgpu-unified-linux-20-50 Mesa drivers got updated to 20.2.4. Seems like they are still working. libva info: VA-API version 1.7.0 |

Thanks @Klauerstoff ! I can confirm this works on Ubuntu 20.04.2 as well after installing 20.50 amdgpu drivers from here: https://www.amd.com/en/support/kb/release-notes/rn-amdgpu-unified-linux-20-50 :) |

Shadow screen also flickering somtimes if recording the screen/Desktop; "only for note" |
