Comment 3 Fabio 2024-11-23 16:29:37 UTC
Disable H.264 and use RemoteFX instead. This is a bug related to alpha channel handling with freerdp2, that we won't be probably able to fix until we'll use freerdp3.
Comment 4 Fabio 2024-12-07 16:53:25 UTC
Currently krdc can be built against last freerdp3 version where this bug is fixed.
