Hi everyone.
This article comes from QubesOS forum:
https://forum.qubes-os.org/t/icons-on-panel-just-show-a-qube-instead-of-its-applications-icon-minimal-template/11416
(Sorry new for the forum, cannot include link on post.)
To conclude, I’ve followed the guide from kicksecure’s wiki, morphing debian-minimal template to kicksecure, and install lkrg, tirdad dkms modules, and enabling hardened-malloc.
I found that after enabling/installing hardened-malloc(both of default and light), the issue comes out as title says.
The whonix-gw template and its appvm also have the same situation so I am here to ask for help.
