Public bug reported:
Time to time, pcmanfm in Lubuntu starts eating 100% of one core (so in
fact 25% of all CPUs in my case according to lxtask). I don't have any
window running but if I have them, they are still open. I'm actually not
sure if they are still usable (last time it happened I had none open).
Desktop (controlled by pcmanfm by default as far as I know) changes
color to black and resets zoom for icons. Icons are still visible and I
click them and open whatever is associated, right click works as well.
In top I can see:
PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
20 0 837144 30096 21252 R 100.4 0.8 33:28.82 pcmanfm
You can see 33 hours but I don't think that it is a time because I don't
remember that it would somehow correlate with how long I run the
computer. It can be related to changing resolution or screen, I do this
often.
