5 months later:
- VirtualBox 7.0.16 released crashing the host with Ethernet in bridged mode -> Useless release
- VirtualBox 7.0.18 released, same problem, no progress.
- Next release: Unknown, no plan.

We can no longer use VirtualBox in a business environment and are phasing out VirtualBox.

FYI: I've been in contact with the assigned engineer, and he gave me the following information/workaround about the flickering.
The root cause of the flickering already understood: sometimes a screen content overlaps in VRAM with a screen update.

But fixing the reason of such "overlap phenomenon" may take some time.

The simplest workaround for now is just choose X.org session type in GDM instead of Wayland as described here, for example:
https://askubuntu.com/questions/961304/ ... untu-17-10
Switching back to xorg took care of the issue for me, and am now running a 6.5 kernel on both 7.0.14 and 7.0.18.

Just adding my voice to the chorus of those experiencing this issue, however in my case reverting to X11 didn't help. In my case using X11 requires 3D acceleration to be enabled otherwise it crash loops before the session starts. With 3D enabled I get the same flickering and corruption under X11 as I do under Wayland.

Without 3D acceleration I can run a clean, if slow, Wayland session for a period of time before the entire GUI freezes. Under Ubuntu 22.04.4 that time period is 7-10 days which is workable. Under Ubuntu 24.04 it's give or take five minutes which is not.

I am now on 7.0.18. Hoping the resolution for this comes sooner rather than later as I would like to upgrade Ubuntu.
