Heavy graphic glitches when using Virtio with 3D acceleration Description of problem: Virtio with 3D acceleration enabled under "Video" and the corresponding OpenGL activated under "Display" with Spice leads to heavy artifacts in the graphical console. This error has been observed on Arch Linux with Intel Meteor Lake CPU (Intel Arc Graphics iGPU) as well as on OpenSuse Tumbleweed with Intel Kaby Lake CPU (Intel HD 630 iGPU) ![virtio_without_acceleration](/uploads/4a05041c944493736f22a013b74c5089/virtio_without_acceleration.png) (virtio without acceleration enabled) ![Glitch_virtmanager_virtio](/uploads/50602ff94dc22f20af77c4b8d487a22d/Glitch_virtmanager_virtio.png) (Same VM, same settings, but with 3D acceleration and OpenGL enabled) ![signal-2024-11-09-132624_002](/uploads/afe1ddedc17725ad9db21eb6f4e1554d/signal-2024-11-09-132624_002.png) (Same issue on a fresh install of OpenSuse Tumbleweed on a system that is in no way linked to the first one) Steps to reproduce: 1. Enable Virtio Graphics with 3D acceleration under "Video". 2. Activate the corresponding OpenGL under "Spice". 3. Start the VM and open the graphical console.
