Late stable update Gnome distorts the image wallpaper on one of the two monitors

I use two monitors -
1 - 1366x768 (16: 9)
2 - 1250x1024 (5: 4)
I use expand monitors.
I use wallpaper option to display background images. I use variety to change images.
After the last update of gnome, this option distorts the image on one of the monitors.
