Black screen when turning off and on again a monitor with DSC

Hello,

I use a 4K 144 Hertz monitor, to achieve this frequency I need to use DSC (Display Stream Compression).

I have disabled DPMS because I just switch off manually my monitor when needed.

  • With DSC enabled switching the monitor off and on will result in a black screen;
  • With DSC disabled I can turn off and on the monitor without issues.

Hence it seems to me an issue with the driver related to DSC.

I have a LG UltraGear GR93U 27" 4K 144 Hertz and a 4070 Super.

I’m using 570.144 drivers from Fedora’s RPM Fusion, I don’t have much time these days to play around with the ones from NVIDIA.

Thanks for your attention!
