Some icons on macOS Tahoe turning dark instead of following selected theme

Yesterday, I updated my 2021 Macbook Pro (M1 Pro, 16/512, 14") to macOS 26.0 (Tahoe). I was excited to try out the new icon theming, and it works just fine, for the most part. However, in applications such as Firefox and Chrome, any action that causes the icon to change such as downloading a file (progress bar appears below icon) or receiving a notification causes the icon to become monochrome and lose its transparency (see example below).

Icons immediately after selecting a theme in appearance settings:

Icons after Firefox is used to download a png from google images:

Things I have tried to fix the issue that do NOT work:

Choosing a different theme from appearance settings

• Locking and unlocking the device

• Quitting and reopening the app

•

Things I have tried to fix the issue that work, but only temporarily (until progress bar/notification dot appears again):

Restarting the dock app from activity monitor

• Removing then adding the affected app back to the dock

• Rebooting

Any help would me much appreciated. The new tinted icons look great, but this one thing is making me regret updating a little bit.

Ok— not all third party apps may be compliant(?)

another example: here is SapmSieve:

—Have you shut down and restarted more than once since your upgrade?

—you can try updating the app and compare your results...

—you can try removing the icon form the Dock and drag a new one down from the applications folder...

good luck !

To be proactive you can file a bug report / submit your Apple Feedback here: Product Feedback - Apple

I would give third-party app developers time to sort it out. For example, the MS 365 dock icons all follow the theme, but yesterday when the MS 365 auto update app popped open, it was black like your screenshots show. So even within one developer, they don’t have it together. Yet.
