Desktop background corrupted after resuming from Suspend

[Alessandro]

Whenever I resume from Suspend I am greeted by this corrupted wallpaper: see image attached.

When I log out the background image shows again for a second before the process (of logging out) complete.

Same issue on 18.1. I'm using a laptop with a 940mx gpu on proprietary nvidia driver. The issue only occurs when using an external monitor.

I'm also having this issue on 18.1 with nvidia 375.39-0ubuntu0.16.04.1

i have to go to system settings, backgrounds, set another background, then set the initial background to get my normal desktop background back.

alt f2 + r doesn't work

cinnamon --replace doesn't work

as a workaround we can switch back and forth between the original and another wallpaper on resume with

don't ask me what the best / save way to do this is but based on this (which doesn't quite work as the background isn't reloaded)

i've found a workaround:

create a file /<email address hidden> with:

[Unit]
Description=User resume actions
After=suspend.target

[Service]
User=%I
Environment=DISPLAY=:0
ExecStart=/bin/sh -c 'old=$(GSETTINGS_BACKEND=dconf gsettings get org.cinnamon.desktop.background picture-uri); GSETTINGS_BACKEND=dconf gsettings set org.cinnamon.desktop.background picture-uri ""; GSETTINGS_BACKEND=dconf gsettings set org.cinnamon.desktop.background picture-uri "$old"'

[Install]
WantedBy=suspend.target

then run

sudo systemctl enable <email address hidden>
sudo systemctl daemon-reload

on resume it unsets the background and sets it new based on what the initial value was.
initially i wanted it to read the current background settings say file://path/test.png, copy the file to a duplicate file file://path/test.dup.png then switch to test.dup.png and switch back to test.png

but i think this is good enough now.

still this only fights the symptom. there's an issue that needs to be fixed.
