Hardware Info

Issue
I upgrade to mint 21 and I have much Gjs-CRITICAL errors in .xsession-errors log file.
BTW, upgrade history - LM 19.3 -> LM 20.3 -> LM 21
21 successfully updated without any problems. I use the default install options - ext4, swap, etc...

Object St.Button error
Object Cinnamon.GenericContainer error
Object St.Bin error
Object St.BoxLayout error

On fresh install of LM 21 i have the same problems.
I found how to reproduce "St.BoxLayout error" and "Object St.Bin error" :

1. Try to move elements in the main menu
2. Try to close the application by mouse middle click. Pinned application does not throw an error.

Fresh Linux Mint 21, VirtualBox, how to reproduce errors

I don't know how to reproduce Object Cinnamon.GenericContainer error. This error occurs the most times in the .xsession-errors

These things really aren't new for the most part, but before they were never logged. Now they are, which is actually nice - we can identify and eliminate them.

I'll leave this open until we can have a look at the specific cases here.

Thanks

I have one more (I've upgraded from Mint 20.3 to 21):

Check timers and handlers. I'm looking for this type of error on an applet I'm developing.
