That bug report is atrocious.
But at least you added this response to a comment:
Although Deepin and Cinammon are also installed on this system.
So thats slightly more information than filing a bug with nothing but a screenshot of the Monitor.
Seriously - have more respect for other people than that.
…anyways…
… I didnt ask you what branch … I asked you if you were using git packages.
pacman -Qqs '\-git'
