I believe the issue is with the 4.14 version of xfce4-panel, but I am no expert in the UI to be certain. I have a version of kali running xfce4-panel 4.12 and it doesn't have the issue. Please see the image below to see that I am missing the GTK3 HeaderBar. This is a problem no matter what application I try to run. Many of the applications such as Burp can't be moved. Anyone else running into this issue or know of a fix? I wasn't sure where to post this so if another forum is the way to go, please let me know.
Edit: This is an AWS instance.
uname -a
Linux kali 5.3.0-kali1-amd64 #1 SMP Debian 5.3.7-1kali2 (2019-11-04)
CONFIRMED: After installing a fresh 2019.2 AWS Kali instance, I then ran apt update; apt install xcfe4. After a reboot, the GTK3 HeaderBar is no longer appearing on any window inside the instance. I'll reach out to that community for assistance, but if anyone knows how to fix it, please advise.
SOLVED: Installed TigerVNC and everything is working with a fully updated 2019.3 Kali
