So I am trying to build hyperion.ng on Libreelec(matrix) and RaspiOS. either way it fails with hyperiond DISPMANXGRAB : <ERROR> Snapshot failed: -1 This happens no matter what OS as long as it is this new kernel. Does anyone know what I can do to fix this? I should say this is a pi4
Side Note: This Kernel is the support for HDR so I want it. I do not want to downgrade kernel. I have been waiting for 4k HDR support for so long.
