I having periodic Mate panel crash on Ubuntu-Mate 24.04. System with all latest updates. Looks like panel reloads, widows buttons on panel change order, and show me request to report this error. If I choose send report nothing happens after this. Where this report was sent and is it sent or not? What may be reason of this problem and is this possible to fix it?

Hi, @Aleksey and welcome to the Ubuntu MATE Community!
When an application crashes apport bug reporting system creates proper file in/var/crash directory. At the same time /var/logs/apport.log file is created or updated. Reviewing these files may provide some hints on the problem's nature.
The following link may help in finding out whether reports are submitted or not.

Your link helped me to find that my reports was sent to ubuntu. Thank you. How to find are there any chances to fix this problem?

No guarantee that this would eliminate the problem, but it might.
Have a look at saving your customized panel layout after you set it up. The discussion and method was outlined in my earlier posting here:

I think this is different problem. I have problem with panel crash with segfault in time of working not on reboot. I looked some lines in crash log I found and I think it may be related somehow to moving/dragging widows buttons on panel. I not sure about this as I am not an expert.
Is it the panel or the dock that is crashing?
I find that reporting manually to Launchpad gets more traction. Look for the bug there, too, as someone may have provided a workaround or the fix may be available "upstream" (which means it will take possibly years before it gets to your system - but you might be able to install the program using other means than APT).

I understand what you are saying, but I think that if you do
- create your custom panel layout
- save that layout as a named layout
- use that layout as the default layout (by selecting the saved layout by name)
then there is a higher likelihood, in my view, that your panel crashing events will occur less frequently, if at all.
The fact that the placement of the App Launchers (panel buttons) get moved around tells me that somehow the OS is not picking up your preferred/defined layout/placements and trying to recover by using a fallback/default layout.
I do think it is worth a try, if you haven't done so already. After all, it could give you an instant resolution to your headache.

If you hover over the window-list applet on the panel, does it show miniatures of open windows ?
If it does, diable “show miniatures” because it is notorious for triggering panel crashes.

Yes, it show miniatures. But screenshots on miniatures do not updating unlike older version. If window changed it miniature show old screenshot. This is strange.
I can try disable miniatures to test new crashes. Thanks for your suggestion.
Here are some interesting links about it:
from @gordon , who is pretty amazing in GTK
From me, logging crashes and testing the solution.
And a post with a link to the bugreport
