I don't usually do skins with "glass" elements that often. Just a personal preference. However, I just completed a build which emulates Windows 7 Aero for Windows 10 and WB 10. Everything seemed fine at first, but then I maximized a window.
This is what I see when I maximize an explorer window:
Looks fine, right? Now if I click on the taskbar to render the window inactive, I get this:
It's like the section around the address bar and search bar doesn't change state. If I mouseover the area, it fixes itself partially. If I mouseover the titlebar buttons, it fixes the state entirely. The same thing happens when returning to active state.
It's not the graphics I used because here is the active and in active windows in tile view:
The top glass area switches between active and inactive states seamlessly.
Troubleshooting steps I have taken:
Replaced the 4 state semi-transparent image with a solid 4 state image. Same lack of state changing occurs.
Checked other skins that also have the 4 state glass top like my skin. They all exhibit the same behavior.
Sent my skin to be checked on another system. My tester reports the same issue on his system.
Second Issue:
If I open a "modern app" window like taskbar settings in tile mode, I can clearly see that it's using the glass frame section.
you can see clearly that the "stroke" stops before the top meaning it's using the glass section rather than the normal frames like a windows dialog window would. It looks kinda bad to me.
Finally my WB and system info:
Update:
According to this thread (LINK), the Beta 10.8.9.1 (06/10/2021) has fixed both of these issues. From the changelog:
Should fix the glass area at the top of maximized explorer windows not repainting right and store windows now always use glass frames on entire edge vs part
Great news!
