black screen when starting flameshot

[alexandre-eymael]

Flameshot Version

Flameshot v11.0.0 ()

Installation Type

Snap from Snapcraft

Operating System type and version

Ubuntu 20.04.3

Description

When I run flameshot gui, both of my screens go black. It worked when I was using Linux Mint, but I changed my OS to ubuntu recently and it does not work anymore. If I disconnect my secondary monitor, flameshot works as expected.

Here is the error :

Qt: Session management error: Could not open network socket propsReply "An AppArmor policy prevents this sender from sending this message to this recipient; type=\"method_call\", sender=\":1.115\" (uid=1000 pid=14609 comm=\"/snap/flameshot/180/usr/local/bin/flameshot gui \" label=\"snap.flameshot.flameshot (enforce)\") interface=\"org.freedesktop.DBus.Properties\" member=\"GetAll\" error name=\"(unset)\" requested_reply=\"0\" destination=\"org.freedesktop.NetworkManager\" (uid=0 pid=664 comm=\"/usr/sbin/NetworkManager --no-daemon \" label=\"unconfined\")" nmReply "An AppArmor policy prevents this sender from sending this message to this recipient; type=\"method_call\", sender=\":1.115\" (uid=1000 pid=14609 comm=\"/snap/flameshot/180/usr/local/bin/flameshot gui \" label=\"snap.flameshot.flameshot (enforce)\") interface=\"org.freedesktop.NetworkManager\" member=\"GetDevices\" error name=\"(unset)\" requested_reply=\"0\" destination=\"org.freedesktop.NetworkManager\" (uid=0 pid=664 comm=\"/usr/sbin/NetworkManager --no-daemon \" label=\"unconfined\")" "Object path cannot be empty" flameshot: info: Screenshot aborted.
