[Bug 2154262] [NEW] Stonking: Incorrect rendering in console

[Heinrich Schuchardt]

Public bug reported:

I tried to install a VM from stonking-live-server-riscv64.iso
2026-05-24.

When moving between screens the old screen is not completely cleared and
one sees output both from the old and the new screen. In the example
below the keyboard layout screen is not completely cleared while we are
at the selection of the installation type. The installed subiquity snap
is  26.04 (7229).

It is strange that the stonking-live-server tracks
26.04/stable/ubuntu-26.04 and not 26.10/stable.


Please select the layout of the keyboard directly attached to the system, if any.                                                                                                     Choose the type of installation                                                                                                                                                       [ Help ]

     The default install contains a curated set of packages that provide
a comfortable experience for operating your server.

     This version has been customized to have a small runtime footprint
in environments where humans are not expected to log in.
