"import" processes continuously taking screenshots


Since a few days I’m noticing that every few minutes my laptop’s fans start screaming. From htop I see a lot of import processes, as shown in this screenshot:

As you can see there’s a lot of those, taking screenshots of my windows and saving it to a temporary folder. When it happens it lasts about 1 minute.
I suppose that the purpose is creating the previews of my windows for displaying them when I press Alt+Tab, but it happens too frequently and it takes too much resources for being a normal behavior.
Besides the CPU and the fans, I’m also worried about the amount of disk writes this process is doing.

I’m running Manjaro Budgie on a Dell XPS 9560.



Can you show the PPID (parent ID) for all these import proceses? And not only the PPID but the full command line of that command.



It’s Budgie preview



Incredibly strange. I ran htop for a minute or 5 now. Max cpu usage was 1.2 % on backgrounder and/or import. Is this an unmodified version of previews? What graphics driver is used?
Previews creates window previews according to an algorithm, monitoring a.o. window z-order change. Unfortunately, I cannot reproduce the issue on Ubuntu Budgie.



Yes, I simply added the Window Previews in the top Panel.
