First: I love DisplayFusion. Thank you <3

OS: Windows 10 Pro version 1809 build 17763.253
Monitors: 3x Horizontal Setup

I currently have "Transparency effects" enabled in Windows, I was wondering if there was a way to add a solid color (black) to the taskbars rendered by DisplayFusion instead of it having mimic the Windows taskbar on the primary monitor?

Thank you in advance. <3

I have a similar issue:
On Windows 10 v1809, the DisplayFusion taskbar is always transparent using what looks like the color of the current wallpaper underneath for its background. Is there anyway for the DisplayFusion taskbar transparency to be disabled? I want it to match the Windows taskbar which is always black with no transparency. I tried changing the DisplayFusion transparency settings to 100% and turning off the Windows transparency effect and accent & titlebar colors but that did not work. Is this a known issue or a problem with Windows 10?
Thanks.

Yes, I do have classic shell installed. The customize taskbar setting was not enabled, so I enabled it and set it to opaque and low and behold that solved the issue. Now all taskbars are opaque, just the way I want them. Thanks for the tip! Excellent program btw!
