AMD card in XFCE has short window hangs and mouse move problem

Hi,  I just bought me a AMD RX 9700 XT. And now I'm recognized a strange behavior in XFCE:

1. When I move a window over the screen, it hangs for some milliseconds until it appears on the final position.
2.  When i move the mouse cursor little bot from left to right all the time over the mousepad the cursor on the screen goes to the left or right screen corner.

Both problems happens only with XFCE. For example with cosmic desktop it's fine.

Because I'm new using a AMD card, I don't know I just set wrong settings.

For example, which is the right driver for the xserver  "amdgpu" or "modesetting"?
Is the arch wiki really up to date for AMD cards?

Re: AMD card in XFCE has short window hangs and mouse move problem

I found something out:
In the xorg is a setting SWCursor. With it both problems are solved for me.

My current setting:

> vim /etc/X11/xorg.conf.d/40-amdgpu.conf

Section "Device"
    Identifier "AMD GPU"
    Driver "amdgpu"
    Option "SWCursor" "true"
    Option "AccelMethod" "glamor"
    Option "DRI" "3"
    Option "VariableRefresh" "true"
    Option "TearFree" "false"
    Option "DynamicPowerManagement" "true"
EndSection

However, I guess a better solution would be the wayland backend instead of xorg. But I guess it will take a while before it's usable in XFCE.
