Description Andrea Antolini 2017-10-29 16:45:23 UTC 
Created attachment 362494 [details]
g-c-c. background setting

- ArchLinux 64 bit
- gtk3-3.22.25
- xorg-server 1.19.5-1
- xf86-video-nouveau 1.0.15-2
- gnome control center 3.26.1

... after recent update of gtk3 libs from v3.22.24 to 3.22.25, the current wallpaper preview in the gnome control center / backgroung setting page  is no more displayed: instead of the current wallpaper preview,  you can see only the preview  of gnome-shell top panel 

The lock screen image preview is displayed without any issue

I've attached an evidence of the issue...

fyi , downgrading gtk3 lib to ver. 3.22.24 solve the issue 

Obvioulsy feel free to reassing bug to the correct team if this one is not related to gtk3 libs

Regards 
Andrea

just updated to gtk 3.22.25 on my Arch.
This bug disappeared after restart Gnome session.

... I've just noticed that issue doesn't occurred if you use wayland as graphic server but  on my archlinux box, as I wrote , I usually use X.org due to some issue with wayland...

btw the simple restart of gnome-session or X session doesn't solve the issue (at least for me)

What backend(s) have you observed this on?

During update process I was running X11.
After update I restarted Gnome using Wayland.
Currently I can confirm the bug described here under X11.
No problem under Wayland.

Reverting 7961e61c3b9e052b0725ccf28665796a7d467e43 fixes this for me.

The gtk behavior changed here, because the previous behavior was wrong.
This will likely require changes on the control-center side.
