No mouse pointer in Solaris/Mac 9 vm on MacOS 11 x86

I have installed the version of UTM today from the App Store (3.1.5 53)
on my iMac 27 Intel with current OS 11.6.4 and tried the VMs of
Solaris 9 and MacOS 9 from the Gallery.
I did not change any options.
They install and boot, but I have no visible Mouse Pointer.
The Mouse is there, I can see the results from clicks, and also moving the
mouse from and to the vm works, but it is not visible inside the VM.
A pointer is displayed when the VM starts (usually in the middle), but upon
the first movement with the mouse it vanishes.
There are no issues on the host MacOS 11.
I have a brew installed QEMU emulator version 6.2.0 running
with no issues.
I use a Logitech MX Master 3 via bluetooth.
