Created attachment 140569 [details] Screenshot of the issue. SUMMARY Using Breeze for the GTK theme, the close button icon is neither scaled nor positioned correctly (centered). The Adwaita theme does not suffers this issue. Please see the screenshot. The app in question I use is the XMPP chat app "Dino" and there it happens for the close button in the CSD title/toolbar of the dialog for the account's settings. The close button of the main window is not effected by the bug interestingly.
