Windows 10 taskbar partially/fully transparent after Creator update

Ever since I updated to the Creator update, my taskbar has been partially invisble. It doesn't impede the function at all, but it's starting to get extremely annoying. My taskbar is in auto-hide mode and has this continuous invisible strip at the bottom, like this:

When the taskbar isn't in auto-hide it gets even worse:


I've tried several 'solutions' that I found online, including restarting, switching auto-hide mode, changing icon size, and running a command in the console that was something about scannow... I can't remember.

Please help me fix this, It's slowly driving me insane.
Thank you.

Do you have Transparency turned on ? Action Center\All settings\Personalization\Colors. Turn Off for solid color. See screener -

Transparency wasn't on. Turning it on makes the taskbar whole, but turning it off again brings the problem back. Strangely enough, when transparency is on, it doesn't matter if the Start, taskbar, and action center box is checked. The problem goes away when transparency is on at all. This seems like a deeper issue than I suspected
