Color palette to white after using Mondrian squares

[PabloAB]

byobu version 5.125
tmux 2.6

Steps to reproduce the bug:

1. Activate the (BTW useless) Mondrian squares feature: Ctrl-Shift-F12
2. Regardless of closing or not the Mondrian window, open a pane on other window.

From now on ALL the line that separate panes will be full-solid white. F5 only brings back to default orange the lines around active pane ($BYOBU_HIGHLIGHT ?). The other lines (pane-border-style ?) keep solid white.

Before and after this environment variables stay intact:

$ echo $BYOBU_ACCENT $BYOBU_DARK $BYOBU_LIGHT $BYOBU_HIGHLIGHT

\#75507B \#333333 \#EEEEEE \#DD4814

Same this file, it doesn't change:

$ cat ~/.byobu/color.tmux

BYOBU_DARK="\#333333"
BYOBU_LIGHT="\#EEEEEE"
BYOBU_ACCENT="\#75507B"
BYOBU_HIGHLIGHT="\#DD4814"

Things I tried and doesn't work and resources:

- rm ~/.byobu/color.tmux
- F5: Reload profile, refresh status
- Alt-F5: Toggle UTF-8 support, refresh status

Not sure if this project is abandoned (last release more than two years ago), but FTR, I mention this bug on Askubuntu:
