There is a bug with customized background. When I set it, I got black background in global menu instead of blured. Not a critical bug, but looks ugly.

Are all you guys using none-free nvidia drivers by any chance?

Inmy case, yes. Non free drivers enabled. Is there a workaround at least?

Hi Dany, yes I have the fix,

I use archlinux with the deepin desktop environment and I was getting the same problem. After doing some research I came across the fix,

Apparently for the blur effect to work, your gfx card drivers have to be DRM enabled, turns out the nvidia non free drivers are not enabled by default.

Like I say I am on archlinux and I have it working, I made a video for arch users: https://youtu.be/5qqs_daBoA0

Not sure what the procedure is for debian, should be easy enough though. Below is the procedure for archlinux.

According to the developer of the blur-effect you need a DRM enabled gfx driver, nvidia (non-free) drivers are disabled by default.

How to enable DRM in non-free nvidia drivers

Goto etc/mkinitcpio.conf add this line under MODULES

MODULES="nvidia nvidia_modeset nvidia_uvm nvidia_drm"

In a terminal do

sudo mkinitcpio -P

Open your grub file found in /etc/default/grub and add this to it

nvidia-drm.modeset=1

eg
GRUB_CMDLINE_LINUX_DEFAULT=“quiet nvidia-drm.modeset=1

Update grub
sudo update-grub

Reboot

Make sure you remove the ‘blank image’ from /var/cache/image-blur

You now have a DRM enabled nvidia gfx driver and blur-effect will work.

Enjoy !!

For deepin (not arch) it is enough to make grub file like this:
GRUB_BACKGROUND="/boot/grub/themes/deepin/background.png"
GRUB_CMDLINE_LINUX=""
GRUB_CMDLINE_LINUX_DEFAULT="splash quiet nvidia-drm.modeset=1"
GRUB_DEFAULT="0"
GRUB_DISTRIBUTOR="`/usr/bin/lsb_release -d -s 2>/dev/null || echo Deepin`"
GRUB_GFXMODE="1920x1080"
GRUB_GFXPAYLOAD_LINUX="keep"
GRUB_THEME="/boot/grub/themes/deepin/theme.txt"
GRUB_TIMEOUT="5"
GRUB_VIDEO_BACKEND="vbe"

And update grub using "sudo update-grub"
