Public bug reported:
VTE 0.80 + GNOME Terminal 3.56 (about to debut in Ubuntu 25.04) add a
new feature: showing progress in the tab bar.
Open multiple tabs (since unfortunately the title bar doesn't show the
progress), and in one of them execute a command such as
printf "\e]9;4;1;33\e\\"
The last number is the percentage to show. You can even animate:
for i in {0..100}; do printf "\e]9;4;1;$i\e\\"; sleep 0.2; done
and finally remove:
printf "\e]9;4;0\e\\"
When using a light GTK theme, this progress arc is barely visible. The
tab label, the inactive area of the circle, and the active area of the
circle are all very similar shades of light gray.
The arc is nicely visible in dark theme.
Upstream GNOME Terminal doesn't suffer from this issue. The progress arc
is clearly visible there in both dark and light GTK themes. So it looks
like it's one of Debian's or Ubuntu's patches that breaks it.
