Gwenview shows "Transferring [Finished]" for each image while viewving

Hi,
just installed brand new 13.2 64bit system

I noticed one annoying thing with Gwenview. When I watch photos in mounted samba share - Gwenview transfers every file and shows notification in taskbar:

This only happens for mounted samba share and if file is quite big (somewhere 5MB or more).

Steps to reproduce:

  1. upload some photos to samba share
  2. mount -t cifs //server/share /mnt/rw
  3. open Dolphin and navigate to /mnt/rw
  4. double click a photo to open with Gwenview
  5. notice the notification “Transfer Finished”
  6. hit Space to load next image - again notification

Tried to uninstall KIPI plugins - didn’t help. Installed back - still same

Anyone knows to get rid of those “transfers”?

Thanks
