Hi,
Extracting the themes breeze/
and breeze-dark/
from usr/share/icons/
inside the data.tar.xz
, which is inside breeze-icon-theme_5.115.0-2_all.deb into ~/.local/share/icons/
solves the issue, at least for now.
Something will need to remind me to remove ~/.local/share/icons/breeze
and ~/.local/share/icons/breeze-dark
once the bug #1079542 is fixed.
