Comment 10 for bug 1647603

pad, the kyboard transparency actually works a bit different. Buttons are a separat layer atop the backdrop. These two layers can have same opacity set, yet they seem to be composited as a sum of opacities. Besides, making only the background of the keys partialy transparrent ould defeat the goal, because the keys surface would still hide most of the area (almost all) of what's under the keyboard. Unless you actually meant everything except the letters inside the buttons, meaning, everything except for just ythe letters (font). Not sure how that would work out, interesting but I'm still in doubts.
