PG32UCDM bios MCM108 broke KVM for me

I have a work laptop hooked up to usb-c and my PC on displayport-1 w/ the usb uplink.

When I flip between systems, the one I'm selecting is usually in sleep mode. On firmware MCM105 it would change the USB with the display connection, so I could wake up the computer and it was perfect. Now when it switches because the video is blank it won't toggle the USB. I have to wake up either of the computers manually and then wait for the usb to re-connect for it to work.

If I try to turn auto-kvm off, the usb connection stays on which ever upstream USB I choose.

This was not the prior behavior. Unless I'm missing something this is a huge regression.

I'm experience the same issue, when I switch between my mac and my pc, the mouse and keyboard transition flawlessly to the display port paired with the usb-b but when turn back to the usb-c it doest switch, that was not a problem in the previous firmware. I have to manually change every time.

If you have it set to AutoKVM it works a little bit better, that's what I 'm using now. But both machines need to be awake for it to work like it should.If a machine has slept the video it doesn't work properly.

Having the AutoKVM off, is how I was previously using it and it worked flawlessly and now works now how you are descirbing, where switching always requires manual intervention.

This feels like a regression that should have been easily caught. Who ever is working on this part of the firmware feels like they've never worked with a KVM before.
