Windows 10: UWP icons dark on taskbar

I have started using some UWP apps and have pinned them to the taskbar. But on some PCs, the icons are dark so they cannot be seen. I can click the spot where I know they are and start the apps, I just cannot see them.

Initially, I thought it was an issue with Start10, but even after fully removing it the problem is the same. Things I've checked:
1) uninstall Start10 and reboot
2) Taskbar Settings -- identical between machine with dark icons and one with normal icons
3) right-click desktop and 'Personalize.' Every setting in Background, Colors, Themes, Taskbar, etc. is identical across machines. Default Windows mode is 'dark' and default app mode is light, transparency effects off, etc.
4) delete iconcache.db and reboot

This is driving me nuts because I cannot find a solution anywhere online. Any help is greatly appreciated! I'm on 1903 most recent non-Insider build, but this was an issue even with 1809. I just never bothered trying to figure it out until now.


I'm attaching a pic of a working one & one with dark icons. On the right-side of each image are icons for the MS Calendar and To-Do UWP apps, you just cannot see them on the second image.

Icons of UWP/Metro apps not showing in taskbar





Icons of UWP/Metro/Modern apps (first gap in the image is Edge, second (the active app) is mail, third is Twitter) are not showing up in the taskbar, nor when they're pinned, nor when they're opened. Icons of classic desktop (Win32) apps are visible. Icons
from the right to PowerShell are pinned, from Slack to the right are just opened.

I've tried several reboots, upinning and re-pinning the apps and a script suggested here: Icons pinned to task bar are not displayed properly on Windows 10.,
but my problem isn't solved. Any ideas?
