isn't the latest Windows 10 build 20H2 (OS Build 19042.1052), after the updates? After installing Windwoblinds 10.8.9.0 beta I started having issues with the system tray/taskbar area, it would get all garbled up, I'd have to move my taskbar into the vertical position to fix it, then move it back to horizontal; this happened every time I'd apply my skin I was working on in SKS, got annoying, so I turned on/enabled "News and interest" to show icon only, and it's been working fine (for now).
Are you sure installing WB had any impact on this?
There is a serious bug in the latest OS update, but WB isn't one of the apps that exposes it. Fences will, Groupy will, WindowFX will, some other apps including some MS ones will but as best I can tell not Start10 or WindowBlinds.
Do you have any of those installed?
