I work remotely on a virtual machine running gnome 3.28.2 on RHEL Server 7.6, the issue occurred when logging in.
I have no taskbar, background, or topbars on any windows, meaning I cannot close or resize any windows and I cannot logout. I can move terminals, but no other windows, and many windows will not alter their z-position when I try to use windows underneath. Alt+tab will not allow me to switch windows either.
I have spent several days searching for answers and trying the fixes found here and elsewhere for similar issues but no such luck!
All other users are unaffected, and rebooting the machine did not solve it. Because of the other users, I am unable to do any more reboots or make changes to anything outside of my /home so as not to affect their work.
I appreciate the first response will likely be the classic "provide more information", but I am not sure what that would be, so any pointers would be greatly appreciated!
