SUMMARY
Since the last update, adaptive transparency of the task bar doesn't work anymore : it always stay transparent instead of becoming opaque when something is full-screen. It should adapt to current windows status (as before).
(If someone want the bar to always be transparent, the transparent option is here. Now we have two option doing the same thing.)
(also, I think that the transparency effect of the start menu is too low. It's hard to see that it is transparent.)


STEPS TO REPRODUCE
1. Put a background with a very colored and saturated color for the transparency effect to be easier to see. Also it should be a different color from the task bar.
2. Put you task bar (or any panel from your layout) to Adaptive transparency
3. Make a window in full-screen and see if you can see color through your task bar.
4. You can also compare "Adaptive" to "Transparent" and "Opaque".

OBSERVED RESULT
It's always transparent. (Not very visible if the background is not appropriate because it's very blurry and it add his color on top of the transparency effect.)

EXPECTED RESULT
Adaptive should be opaque with full-screen window or when windows are covering all the background (probably with splitted windows) and be transparent when windows are all floating or minimized.
