The OSC sequences sent by flatpak-builder are meant to update the window
title (See https://terminalguide.namepad.de/seq/osc-2/).  I plan to
provide an osc-compilation-filter (modelled on
ansi-color-compilation-filter) to be added to compilation-filter-hook.

One possible mode is to filter out all osc sequences.  An other mode
would be to call per command handlers as done by
comint-osc-process-output.

Any thought?
