Windows 11 VM black screen when expanded to Full Screen mode #3631

Wondering if it's too large for QEMU's graphics driver to handle. Can you, for testing, change your Mac's screen resolution to something low like 1080p (no retina) and see if you still experience this? |

Just tried and checked it's working fine when it's running on lower
resolution.
1920x1080 (no retina): works without issue
2560x1440 (no retina): works without issue

I can reproduce this as well. With "Retina Mode" enabled going into full screen on a 4K display causes the VM to show black screen. Without "Retina Mode" the VM resizes to 1080p as expected and works fine. |

This issue still exists in 4.1.5 |

I have the same issue with version 4.1.5, SPICE Tools installed, "Retina Mode" enabled, and an LG UltraFine 5K monitor.

It looks that the limit for the Windows guest resolution is 7.5*1024*1024 pixels (so e.g. 3840x2048 or 4096x1920) and it is probably a limitation or bug in the virtio graphics driver for Windows. I reported this in the |

The issue still exists in 4.4.4 |

still exists in 4.5.2😢 |
|
Still exists on version 4.5.3. |

+1 - issue still exists on 4.5.3 |

Using 4.5.3 having same issue. But in my case i get black screen after win login with/without fullscreen mode enabled. |

Still exists in v4.5.4 (100) |

@maddoglee As I mentioned in utmapp/virtio-gpu-wddm-dod#4, the limit seems to be exactly 7864320 pixels (7.5*1024*1024) in area. You can go beyond 3750 horizontally if you use less vertical space, e.g. 3840x2048 is fine (and exactly at the limit). This is especially annoying because the limit is below some common resolutions, e.g. standard "4K", i.e. 3840x2160, is 8294400 pixels (i.e., ~7.91*1024*1024). |

Ahhh I missed your other post. Thanks for the explanation! |
Describe the issue
Screen.Recording.2022-02-16.at.12.05.49.480p.mov
I have Windows 11 21H2 VM with SPICE 0.164.3 running. Resolution changes as I resize the VM window without issues. However when I expand the window into Full Screen mode (Globe+F or 🟢 button) the screen goes black and will not adapt to my monitor's full resolution (3840x2160). When I exit Full Screen mode the VM comes back to normal.
