I´ve got a question concerning my mouse-pointer.
From time to time my mouse-pointer changes to a symbol that represents something like an arrow melted together with a loading-circle. I tried to find out something about it and believe that it means "background activity".
So far so good. But there´s one thing I cannot really explain:
Whenever I open my file-manager pcmanfm in a "normal" way, i.e. by clicking on a desktop-icon or the respective symbol in the task-bar, the window immediately opens - without any mouse-pointer activity.
However when I start pcmanfm by clicking the key-combination "WIN-key + e" the window opens as well but with the addition of the "background-activity" symbol. That one can be seen for about 20 seconds and then vanishes.
I use firejail (sandbox) and the associated tool firetools. When opening firetools from the menu there´s the same thing: background activity-symbol for a few seconds. But when opening via command line: no symbol whatsowever.
Just to be clear: everything works fine without any delay - even with that mouse-pointer-symbol. I just want to know why that is?
