I have had this issue since forever, there are a couple other issues like this around but non that quite match the symptoms I encounter when this happens. After boot, 1/3 times only the wallpaper is shown and nothing else for a good minute or so. No desktop icons, no dock, no panel. After a while, all of the sudden something causes the dock and the icons to pop up. But, not the panel. I have to run the panel manually with mate-panel & and then disown.
Note that during the nothing is visible period, I am able to CTRL-ALT-t to get the terminal.
Today I tried mate-panel --replace & instead and got these errors.
prompt:~$ mate-panel --replace
GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface “com.canonical.AppMenu.Registrar” on object at path /com/canonical/AppMenu/Registrar

prompt:~$ mate-panel --replace &

prompt:~$ disown

Someone please help! I can't always wait for my computer to take a minute after boot.
Hi I would save my configuration inside mate tweak, choose a other one, test with a reboot and next customize it again as you want. You can find it here :
Note sure if I entirely understood the tail of your instructions. I saved my panel in the tweaks and changed it to some other style. Logged out and back in a couple times to check if the issue occurs and when it did not, I changed back to my saved panel. After that, I again logged out and back in and the issue did not occur.
However, each time I switched the menu, I got a little applet icon down in the dock and when I clicked on it, it minimised the panel. I had to mate-panel --replace & and disown again to get rid of it from the dock.
PS: What theme are you using? Care to share a link please?
The problem is not resolved. Today when I turned on my computer everything (desktop icons, panel and dock) were gone. Couple minutes later, the dock and the desktop icons came back but the panel did not. I ran mate-panel --replace & which gave the usual,
GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface “com.canonical.AppMenu.Registrar” on object at path /com/canonical/AppMenu/Registrar
Well,
Just checked inside dconf-editor and saw that my side this path do not exist too. Can you remove appmenu from this pannel, reboot and add it again ?
Like I said before, the issue is not deterministic. It sometimes happens and sometimes not. You're suggesting that the issue is with the indicator applet? I don't use the Indicator Applet Complete because I don't want a clock in it.
I am not sure how to try what you have suggested because that might require going with the wrong applet till I observe/not observe this issue again.
Could you explain that error message a bit more to me?
If I got something similar, i would remove whole panel and create one new and configure it again
Next, if still not helping, I would create a new user and migrate my data to the new profile.
Okay so the issue started to appear more frequently and I have narrowed it down to the indicator applets, both including the complete one. Whenever I add them to the panel, I get,
It can be caused by a software that starts automatically at boot and behave in a way that the applet do not like it.
I got something like this with copyq and Global AppMenu - random crashes and this same error message.
Can you check what software is running on logon/at the moment you start have the issue ?
I took a peek at start-up applications and really the only thing that had an icon in the applet was dropbox. I disabled it and it still crashed. Then I disabled almost everything except those that probably kick off the system and it still crashes at start up. It does make a file in /var/crash which looks like this,
This bug report is for vala global appmenu - this applet :
and is exactly the issue I was running into with copyq, but your error indicates issue with indicator-applet and not vala-global-appmenu.
Can you try doing it this way, go to startup applications, identify all startup things and uncheck all not required ones like they done here :
