KRDC connecting to Win 10, but only acorrupted or even noimage at all shows up

15 May 2024, 22:56:12

I've recently installed artix fresh on my laptop. Since then I had some issues with KRDC.
When I connect to my Domaincontroller (Windows Server 2016) everything works fine. But when I try to connect to my Win10 virutal machine in the same network, KRDC acts like it has connected to it, but never shows the image of the remote Desktop. In some cases a completely corrupted image is shown (vertical bars across the screen of a pixel mesh resembling the desktop colors in soime way). This only happens at connecting to my VM. All other connections seem to be fine. STDOUT print the following on connecting to said Win10VM:

k subsystem pulse because of error 12

but if I understand this output correct, it is only related to issues on the sound part. So no errors for me regarding the image?
KRDC is on version 24.02.2
I am using KDE Plasma Desktop with KWIN and Xorg.

Any hints on how to resolve this issue are highly appreciated.
