Installer frozen, stuck at 100% CPU every time I enter 'Your name'

[Daniel van Vugt]

What happened?
On a Surface Laptop 4, every single time I try to install Ubuntu 23.10(.1) it freezes while I type my full name under 'Your name'.

The ubuntu_desktop_installer process is stuck at 100% CPU. It seems to be both the primary thread and the io.flutter.ui thread that are both using 100% CPU.

What was expected?
I can install Ubuntu.

Steps to reproduce
Boot Ubuntu 23.10 from USB. Seems every install option I try results in the same bug and the only common factor is the laptop (Surface Laptop 4).

Workaround
Fill in "Your computer's name" before "Your name".

Bug 2056167 might be the cause here, if it's a buffer overrun of some sort from the bogus default hostname.

The install starts in the background after you confirm the storage choices. Looks like Flutter is also be busy, but there is some competition for resources.

Verified fixed in 20240408, but it might just be the fix for bug 2056167 having worked around it.
