Mine is a fresh install of Ubuntu 12.04, using Unity 2D Desktop, and from the start I have had the issue showing in the first poster's screenshot. The up-arrow and the down-arrow are the same color as the scroll-bar background, and are thus invisible to the eye, the slider itself is light-colored and can be dragged as is expected.. The invisible arrows also work as expected if one is careful to avoid clicking on the background of the scroll bar. Clicking on the background works as expected provided one takes care not to click instead on either arrow.
My Thunderbird is up to version 15.0.1. My Firefox scroll bars have both a light scroll slider and top-and- bottom arrows as should Thunderbird. If anything, my Firefox scroll bar background is a little too light, making very little contrast between it and the slide controls. By the same token, only worse, the Ubuntu Unity color scheme makes no distinction between the title bar and the menu bar under it, and makes no distinction between active and inactive windows either. These issues are for information only, and due for a report under a different bug report. I would welcome the dark color of the Thunderbird scroll bar background together with light controls, or switch them vice versa, and do the same in Firefox. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to light-themes in Ubuntu. https://bugs.launchpad.net/bugs/1025935 Title: Thunderbird 14.0 scrollbars have a wrong background [regression] Status in Light Themes: New Status in Mozilla Thunderbird Mail and News: New Status in “light-themes” package in Ubuntu: New Status in “thunderbird” package in Ubuntu: Confirmed Bug description: I have updated to Thunderbird 14.0 via the update manager recently.
