Monterey 12.1 broke DP1.2?

[ice29]

Since updating my 16" M1 MBP the LG 4k 27" screen that I have been using since years with USB-C to DP cable stopped working properly... Or better said, some apps started crashing when starting (OneDrive, CS:GO, OpenRA...)
When I disable DP1.2 in the monitor menu (it reverts back to DP1.1, with bad colors) all is good, as well as when I use USB-C to HDMI2.0 cable. Anyone with similar issue?

Are you saying that using a USBc-to-HDMI 2.0 cable corrects the problem?

Fishrrman's credo:
Use what works for you.
Ignore what doesn't work...

Yes, with USBC-HDMI2.0 no problems... the same when I turn DP1.2 off

Seems to be working fine here on Intel, maybe the M1s are still having some graphics issues. My Samsung is connected to a Sonnet eGPU with a straight DP cable and 1.2 is on in my OSD.
