After upgrading to the new 6.0.5 flatpak, I noticed that the X buttons for removing specific references are bright red and therefore much too dominant.
How can I remove or darken the red background of the X button?

From the @Dan-cer profile: Linux Mint LMDE 6 and your screen capture indicates youâre using a Dark theme⌠so youâve got the Theme addon installed. And it means that youâre familiar changing your theme selection.
Which mean that this becomes a question about tweaking CSS.
And that starts with 3 items:
To remove the buttons, uncheck the âShow close button in gramplet bar tabsâ option in the General tab in the preferences.
Alternatively you could use a theme with a different âwindow-closeâ icon. Below is a screenshot using the Adwaita icon theme:
![]()
You can use the Appearance tab in the Gnome Tweaks tool to change the icon theme. A restart of Gramps is not required for the change to take effect.
I have unchecked the option.
