+qemu 8.1.0 breaks gvt-g + qemu-ui-gtk w gl=on (black screen, qemu: eglCreateImageKHR failed)
+Description of problem:
+As of 8.1.0, qemu-ui-gtk renders a black window with the error `qemu: eglCreateImageKHR failed` repeatedly appearing in the command line.
+
+
+#
+Steps to reproduce:
+1. enable kernel modules, set parameters etc.
+2. create vgpu
+     `echo "$GVT_GUID" > "/sys/devices/pci0000:00/0000:00:02.0/mdev_supported_types/i915-GVTg_V4_2/create"`
+3. launch VM
+4. wait
+
+Instructions (a small part of which I wrote by trial and error) for the setup are on the [Arch Wiki](https://wiki.archlinux.org/title/Intel_GVT-g).
+
+#
+Additional information:
+Windows is installed directly to a second SSD, I dual-boot it.  
+I've been using this exact VM, from libvirt, for almost two years.

+
+The patched vBIOS necessary to use DMA-BUF with OVMF is linked there too, but its [successors](https://github.com/patmagauran/i915ovmfPkg) doesn't work either.
