Mouse clicking but not moving in some Distros with evDev

[professionelPCbreaker]

Hello everybody,
brief description of my Problem:
I use Proxmox with GPU-Passthrough and two GPUs. To switch mouse and keyboard between host and guest I use evDev. In most Distributions like WIndows 11, PopOS and so on everything works, just with CachyOS (and at least the live version of Ubuntu) the keyboard works fine, mouse also clicks (both right and left) but it just isn't moving. Evtest doesn't pick up any movement. A USB mouse though works.

Additional Infos:
I use Xfce4 on my proxmox host, I know, I'm not supposed to do that, but for the last 2 years everything worked just fine. The problem came a few days ago and I can't think of anything that might have triggered it. For test purposes I used a installation of windows, ubuntu and cachyos in the VM (ID 105). In the windows installer the mosue moves. In a different VM (106) I have PopOs installed, the mouse is moving and in a live version of Ubuntu and CachyOS it isn't.

journalctl -r after the start of the VM shows the following:

I am a bit of a noob, so I am already very sorry for the tones of mistakes I have probably already done and I am very grateful for any help!
Thank you already!

Update: Also tried switching back to xserver-xorg-input-evdev, also didn't work, still trying around with no clue

Since the issue seems to be affecting only some of the VMs and not others, it might be related to how input devices are being passed through or handled in certain VM configurations. A few things you could try:
Check VM Configuration: Ensure the problematic VMs are using the correct input device settings. You might need to adjust the USB tablet or PS/2 settings in the VM's hardware options.
Update Guest Additions/Tools: If the VM relies on particular drivers, such as QEMU guest tools or VMware/VirtualBox guest additions, ensure they are updated. These can affect input device functionality.
Examine Proxmox Logs: Check Proxmox's syslog and VM-specific logs for any errors or warnings when starting the affected VMs. Sometimes the logs give a crucial hint about what's missing or failing.
Compare Software Versions: Since you mentioned everything worked fine for two years, consider whether a recent Proxmox or guest OS update could correlate with this issue. Reverting or reconfiguring after an update may help.
Test Different Display Protocols: If you're using SPICE or VNC for your VM display, try switching to another protocol and see if the issue persists.
