I am currently working on a GTK+ 3 program and I constantly encounter this rendering mistake. The edges around radio buttons are drawn orange which is especially visible when the window is passive and the buttons turn grey. Is this a Ubuntu-Bug or related to my computer?

Depending on your current used theme, you can either (which is more likely and easy found out) edit/change/modify the graphics .svg or .png, like shown in the screen-shot below or by changing the color-coded values for visually drawn window graphics in the themes .ccs files.

  1. Find out, what theme you are using.
  2. Browse through the graphics folders (first) to find a visual match.
    To edit [.svg] files simply use inkscape and for [.png] files gimp. *Install via Software-Center
  3. If it is not imaged-based, go for the .ccs files.
  4. The path/dir to look for is:




Please note: Highlighted/focused buttons, tick-boxes etc.. are all rendered by the default theme itself!

  • Thanks. I have to look at that. Don't you think it is odd that Ubuntu would have such an obvious rendering mistake? I also see it in the radio buttons of the Update Mananger. – tobias47n9e Jul 4 '14 at 15:51
  • It might be a bug (at worst). Only further investigation into the matter will sheds some light on it. Guess though it can be resolved as suggested. GL! – v2r Jul 4 '14 at 15:56
