Progress bar shows no progress until done copying file

I need some guidance. The progress bar does not move at all in the file managers on my Arch Linux system. It stays at zero until the copy has finished. I have tried Nautilus, Nemo, and Thunar, and they all behave the same. I have copied big single files to make sure the progress bar stays for longer, but still, no progress is shown - files copy fine though. I have a Debian system and progress bar shows no problem. Any clue where to look?
