Hi,
after the upgrade to plasma 6 (new Manjaro Version) i could not use my video projector with Wayland anymore. It is connected on the USB-C-Port of my laptop with an usb-c to hdmi adapter.
I see this error in journald:
Mai 29 23:48:01 user-pc kwin_wayland[1484]: kwin_wayland_drm: Couldn't parse EDID for connector DrmConnector(id=339, gpu=KWin::DrmGpu(0x60f9b57cb5c0), name="DP-3-unbekannt", connection="Connected", countMode=37)

It works fine if i use x11, so i think its a wayland+plasma6 thing. It worked before the last big Manjaroupgrade, where plasma 5 was used.
If this is helpful:
