};

Steps of reproduction

1. Enable window shadow
2. systemctl suspend and resume from suspension.

Expected behavior

The window border has a shadow around it.

Current Behavior

The shadow disappears

Maybe picom crashed after resuming from sleep? Did you check if picom is still running?

Yep, picom is still running. And after I resize or move the window, the shadow would come back

[OopsYao]

Can confirm. Resaving the config file or sending USR1 signal to picom also brings the shadow back.

i have a theory that this may be fixed with 37ecb4b, but i’m not sure. would be good if you can test it and report if the issue is gone.

Nope, the issue still persists, and I got a lot of

GLX error at line 479: GL_INVALID_OPERATION

error when resuming from systemctl suspend.

Problem is still or again occuring in Picom v12rc2 (vgit-bc455e), with Nvidia driver 550.107.02.
The following workaround works for me.

sudo vi /usr/bin/nvidia-sleep.sh

# In section "resume)", just above "exit 0", add:

/usr/bin/touch PATH/picom.conf

Change PATH according to where your picom.conf is, in my case the line reads:
/usr/bin/touch /home/tc/.config/picom.conf
