Thanks for the report! You're right, this looks like a regression. Could I ask you to check something in your Windows theming settings? In Settings -> Personalization -> Colors, do you have "Custom" for "Choose your mode"?

[EDIflyer]

Thanks for the reply @mark-dr - yes, you're quite correct:

IIRC I found Windows defaults a bit annoying for folders so have this custom setup!

[mark-dr]

Thanks for the confirmation! Sounds like the icon's syncing with your app theme rather than your Windows mode - this usually happens if we're having trouble reading the registry for some reason. Sorry for the annoyance, I'll look into your diagnostic and get this fixed in our next version (4.39.0) 👍

[EDIflyer]

Haha definitely just an annoyance rather than anything major but any little tweaks to fix much appreciated :)

[zoliszabo]

Happening to me too. Same settings in Personalization > Colors.

[lorand-horvath]

I confirm the issue, the tray icon is black on a black taskbar background, at first I didn't even notice it's there!
Please see below my Windows 10 settings under Personalization > Colors

[iPilot]

It appears that icon is black when app theme is light and vice versa.

[andrey-helldar]

I also have the icon turned black after the last update.

Docker Desktop version is 4.38.0 (181591)
Windows 11

Mode: custom
Windows mode is dark
Apps mode is light
Transparency is on

[MikeWilliams-UK]

I am seeing this too on Windows 10 Professional

[koron]

I had the same issue on Win11.
However, after explicitly selecting Light in the Docker Desktop settings and restarting Docker Desktop, I got a white icon.

[K2ouMais]

To turn the icon to white again you could change to dark mode Docker Desktop.

I am also using a light theme in Windows 11, but I like to have my Taskbar in dark.

The icon color problem is in Windows 10 and Windows 11.

[daniels1989]

Adding on to this: Have the same problem, same Windows settings as the users above (Custom colors, dark for Windows, light for apps), but I've set my Docker Desktop to use dark mode.
Docker Desktop boots on startup but minimizes to the system tray and since 4.38 uses the black icon as mentioned above. However when opening Docker Desktop for the first time since boot it briefly shows in light mode before swapping to dark mode, the icon changes to light mode at the same. This didn't happen in 4.37. So it seems as if the selected color scheme isn't updated until the window is actually opened.

[MikeWilliams-UK]

As the configuration of the windows theme of custom with light apps and dark task bar is the windows default.

Docker Desktop MUST use a sensible (white) task bar icon in that scenario.

Hi folks, Docker engineer here. If you're experiencing this issue, could you try this build and let me know if it fixes it? Thanks!

[EDIflyer]

@mark-dr weirdly it's looking OK just now on my system with my existing install (before trying the new build) - still 4.38.0 (181591), can't work out what changed?

[yastrebf]

@mark-dr Yes, your build 4.38 (182513) fixed this issue. Thank you

[K2ouMais]

@mark-dr your build works also for me. Thank you

[MikeWilliams-UK]

When will this build be avaible via the normal update route?

[mark-dr]

@MikeWilliams-UK, I'll get it into the next scheduled release, planned to go live on Feb 27.

[MikeWilliams-UK]

Thanks @mark-dr
