Transparent background on pfp no longer working when changing on mobile

Transparency only works when you have custom or achievement art selected as background, Try setting an achievement as a background then change back to solid background colour of your choice .

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community

Hello Nykuro, where you're trying to update the image, they've actually changed some image type and format guidelines to Gamerpic, if you're trying to switch across Xbox or the Xbox website, would suggest you try the Xbox App Companion.

I'm having the same issue. Tried hard reset, unplugging the Xbox, changing the background, tile transparency and none of it worked.

A solution can be found here (relevant parts included for your convenience): http://support.xbox.com/en-GB/xbox-one/console/change-xbox-one-background

Adjusting the tile transparency allows you to better view your custom background through the tiles on the screen. To adjust this:

1. Scroll left on the Home screen to open the guide.
2. Select Settings.
3. Select AllSettings.
4. In the Nav pane, select Personalisation, and then in the right pane, select My colour & background.
   
5. Select Tile transparency on the My colour & background page.
   

Choose the transparency value that you prefer (Solid, Mostly solid, Partly transparent or Mostly transparent).

The following additional information is taken from
news.xbox.com/.../xbox-one-xbox-one-february-system-update:

Custom backgrounds and tile transparency – We’ve added tile transparency to the Home tiles to make your background images more visible. As a reminder, to set a custom background, go to Settings > My Xbox > My
background. Note: some items can’t be made transparent due to usage rights/restrictions for certain images.



Let us know if the above solution does not work.

I love the semi-transparent tiles it's good if you add your own photos or pictures to the Dashboard background. I no longer have a Windows 8 UI shouting 'hey I'm Windows 8 I'm going to obscure your Dashboard background pic'.
