Thanks for the feedback. I can't reproduce  issue 3 ). Could you send a screenshot to show which images are repeating?

1) and 2) are intentional. The new wallpaper picker does not show the wallpaper history or factory wallpaper.

> Could you send a screenshot to show which images are repeating?

I prepared a small demonstration video, because there is a whole bunch of duplicated pictures. So I chose one of them - the famous "Aerial view of airliners in the desert" for easy searching. Please, observe moving vertical scroll bar as a confirmation that selected picture is appearing twice on two different places and close pictures around it too.

> 1) and 2) are intentional

And the reason for this is?
Please explain then, how we can now select own custom wallpapers which are saved in Chrome Syncable FileSystem on Google Drive and how we can now select original factory wallpaper which is saved somewhere on the device? Both was possible in previous wallpaper picker version for years.

I have disabled chrome://flags/#enable-new-wallpaper-picker to be able to use these features now, but this flag could disappear anytime in the future.

Thanks for the video!

+James, the duplicate image is a server-side issue. Could you help triage this? Thanks! (You should be able to reproduce the issue on the device I handed to you.)

+Omri, showing the factory default wallpaper is straightforward. I'm working on it now. However, showing the wallpaper history is not part of the new wallpaper picker mock, and now it's quite complex to add them. Do we have a reason why this is not included in the original design? (I assume it's because there're very few users actually caring about wallpaper history?)

Assigning to pujolj@ for investigation on 3) (the image duplication)

I'll land the fix for 1) today.

Thank you very much for such a quick and thorough response.
As a workaround in the future one should download own custom wallpapers from Chrome Syncable FileSystem on Google Drive.

Re #6, thanks. The factory default wallpaper is added back now, and it will be included in M72. (The #enable-new-wallpaper-picker flag will be removed in M72.)

Please use Chrome Syncable FileSystem as workaround for now. Thanks! (Actually, I was about to land code to delete all the history custom wallpapers in Chrome Syncable FileSystem, because we wanted to completely remove the support for wallpaper history, but based on your feedback, for now we'll keep it as an alternative option.)

I apologize very much, but in the opening post I forgot to mention one more issue. I highlighted it in the attached picture, there is sometime displayed remnant of some text.

#3 image duplication has been fixed.

Re #9, sorry! I missed this comment. I can't reproduce this issue though, how often does it happen on your device? Thanks!

Not so often, from time to time, randomly.
I hoped that displayed remnant of some text will be your key for searching in code.
