I’ve had this problem before and it was fixed by reinstalling the appropriate thumbnailer, but this time a reinstall didn’t fix it.
I’m running the MATE desktop, and Caja is often running at 32 percent on the system monitor, despite it not even being open. To be clear, it’s not I’m running Caja, it sticks at 32 percent, and then it’s not shutting down properly… it’s I’m running it and shutting it down, the CPU loads drops to 0 percent, and then much later I can see CPU activity and when I check the monitor it’s always Caja. It’s almost like it’s running in the background despite me shutting it down, and then randomly freaking out at some later point in time.
Not sure what’s going on here… any ideas?
