As I really like the classical Ubuntu orange theme, I am trying to recreate it. I want orange icons, selections, everything. I am nearly there, except for one thing - the progres bar in e.g. the Transmission torrent client, or the progres bar that appears when checking language availability in the Controlor Center, looks like this currently:
[as new new user, I cannot upload an image]
Put shortly, there is still a tiny green bar in the middle of the orange progress bar.
I have tried to go through all the .css files in the theme directory, copied assets from another ubuntu theme, however I cannot yet find where the problem is.
I believe it’s a MATE Bug, something to do with GTK 3 themed apps since I have the same problem too. I recall this bug should be fixed in newer versions of Ubuntu MATE when GTK 3 is fully supported?
Are you modifying the theme from /usr/share/themes?
