Heavy screen flickering VirtualBox 6.1.50 / 7.0.14 Ubuntu guest kernels 6.4 / 6.5

Heavy screen flickering occurs with Ubuntu Wayland guest after installing guest Ubuntu updates.

VirtualBox Forum:

• ​Heavy screen flickering VirtualBox 6.1.50 / 7.0.14 Ubuntu guest kernels 6.4 / 6.5
• ​Graphical corruption with VB 7.0.14 and Ubuntu 22.04.3
• ​Artifacts in Ubuntu 22.04 guest on Kubuntu 22.04 host, Nvidia RTX 3060 Ti

Reproducible on AMD Ryzen 7/9 Windows/Linux host computers as all guests running Ubuntu (Wayland) flavors are affected after updated kernel versions 6.4/6.5:

• Ubuntu 22.04 / 23.10 desktops running kernel versions 6.4 and 6.5
• Fedora 39, kernel 6.6.9-200.fc39
• Hosts Windows 10 and any Linux
• VirtualBox versions 6.1.50, 7.0.14 and older
• Corresponding Guest additions installed
• Guest Display settings: 128MB, 3D acceleration unchecked (as 3D graphics acceleration is not supported by VirtualBox)
• Latest Windows 10 host NVidia driver v546.33

Problems:

• Screen flickering occurs especially in full screen of the guest and maximized guest window.
• Additionally, the Ubuntu 23.10 / 24.04 installation window does not start or is white (popup asks to quit as there is no GUI response).
• Very slow GUI guest response.

@VirtualBox developers: Can you confirm that this bug is reproducible?

3D mode is disabled

I can confirm this bug with Ubuntu 22.04 guest and host. If 3D mode is enabled flickering disappears for me.

Problem exists with Guest settings | Display | 3D Acceleration unchecked.

Hi Erwin,

Yes, the issue is reproducible here. I am not the one who is working on a fix though. I will close this ticket as a duplicate of #21955. Please refer to the original ticket for the updates (you can add "+1" comment there to receive further notifications, just a tip).

[Erwin]

Good to hear that the problem is reproducible. Do you have a schedule when this critical issue will be fixed?

I've explicitly created this duplicate ticket as it is not possible to change the VirtualBox version to 7.0.14 in ticket #21955. I'll ask a moderator again to actively keep tickets up to date.
