Bug with invisible cursor when using GVTg

[HF <hf@xxxxxxxxxxxxxxx>]

Hi,
i am running a Windows 11 guest under Fedora with Intel GVT-g provided virtual 
GPU, which worked fine for over a year, but now, approximately since i upgraded 
from Fedora 38 to 39, i can not see the cursor within the guest anymore.
If the cursor changes (like on the border of a window to stretch it), i can 
see it, but under ordinary operation, its invisible.

My output is via SPICE with MESA EGL by setting 

    <graphics type='spice'>
      <listen type='none'/>
      <gl enable='yes'/>
    </graphics>
    <video>
      <model type='none'/>
    </video>

and for the GVTg vGPU:

    <hostdev mode='subsystem' type='mdev' managed='no' model='vfio-pci' 
display='on'>
      <source>
        <address uuid='af5972fb-5530-41a7-0000-fd836204445c'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x02' 
function='0x0'/>
    </hostdev>
