I currently have the Ambiance theme set and for some reason the tiles(?) in the window tray have the window titles very close in color to the background making it extremely difficult to read.
I was wondering if there was a way to fix it.
--Apparently new users can't post images until they have 10 reps or something. Anyways now most of the time it seems that the window icons ( that is where you click to switch open windows ) has a white background and is visible but sometimes now it will switch to be default Ubuntu gray-ish and the text blends in.
It was probably a bug in 12.04 that's been at least partially remedied.
