Most times after running full screen apps and playing videos (usually KMPlayer or using Chrome/Edge on youtube), I notice that the full screen app (yes i pressed maximize) doesnt cover the taskbar any longer AND the taskbar background color appears to go transparent.
You may think the taskbar is hidden but it isnt. All icons show up and they work.
Closing the app doesnt help. Its broken until reboot.
It also breaks if startdock is disabled the default win 10 menu returns with the background color missing. Opening the menu immediately fixes it. Reboot and notice start10 launches fine but the taskbar no longer paints with the correct theme color (it goes solid black) and will never come back (reboots dont help). It will not ever fix itself. Reboots/power off-on doesnt help
The only fix is to change themes. Reboot. Change theme back. Then its restored.
I believe there is a case where start10 isnt honoring the background taskbar color correctly and that creates these two failure modes. As it stands my taskbar is driving me nuts. Every few hours it messes up
I have included repro steps below with associated screenshots of the issue in numeric order
Check out the enclosed pics. They are numbered sequentially to make the sequence of event understandable.
Thanks in advance.
Happy Holidays
1) Taskbar has green theme applied

2) Here is is full screen. Menu and taskbar are green as expected. Use Settings->Themes to change theme

3) Use Settings-> Colors to ensure the correct checkbox is enabled (start, taskbar and action center)

4) Play full screen videos ensuring you pressed maximize button. Alternate maximize on/off as you play diffent videos (i use youtube and KMPlayer) and after a while you will see what appears to be the video NOT covering the taskbar. Close the app and the taskbar is permanently wrong color

5) Reboots Dont Fix It. Unload Stardock to try to return taskbar color with default Win 10 menu

6) The wrong color is STILL displayed until you press the menu button once. Then everything returns to normal

7) Reload start 10 or reboot and Start10 comes up with wrong color permanently. It will NEVER correctly paint (reboots/power off-on) doesnt help.

8) Ask community for help
