Extreme UI lag when copying files on Nautilus( fedora 25)

[Bill Kontos]

I am encountering a bug that causes extreme UI and mouse lag when copying files using
Nautilus on a fedora 25 installation. The system is up to date as of 9/2/2017. This is
encountered both when I'm copying from a directory on the internal hard drive to
another directory or from a directory from the internal hard drive to a removable media.
Mouse, switching windows pressing super, everything lags. The lag stops when the copy
operation is completed or if I cancel it. 

Is this a known bug with a workaround or should I report it ? If I should report it can
you point me where and how ?
