Wallpaper going all grey with gnome-tweak

[Victor Moreliere]

Hello,

I recently upgrade from ubuntu 18.04 to 19.04. I have noticed that sometimes my wallpaper is completely grey and with some "glitch" (I think it's when i put on stand by my computer and I retart. More over I saw that this display bug appears when I'm in zoom mode with my gnome-tweak's wallpaper but it's working when i'm in wallpaper or centered mode (even if the position of the image is not fine but that was already the case in 18.04).

Good luck.
Sincerely.
