Describe the bug
Minimap buttons are showing a backdrop on top of the icon.

To Reproduce
Steps to reproduce the behavior:

1. Turn on Maps > Minimap Buttons in Windtools
2. View the icons below the minimap
3. Note the gray/black squares on top of some/most icons

Expected behavior
Icons should be clearly visible, like the Altoholic icon in my screenshot (as opposed to the other icons)

Screenshots

Information (you can find these in [WindTools-Information]):

• Addon Version: 2.26
• ElvUI Version: 12.46
• WoW Build 9.1.5

Additional context
I haven't fully tested without other addons loaded, so if this isn't readily reproducible for anyone else, I can try turning off other addons to see if there's another culprit.

Also, while the setup seen in my screenshot (the right-most 6 icons have issues while Altoholic does not) is the most common I've seen, there are times where some other icons don't have the issue present.

I will take a look after asian server updated.

The problem has been fixed in 52db8a7 commit.

Thank you for your reporting with clearly information.
