Nemo reporting false file transfer progress for USBs

[SpeeQz1]

Distribution

Mint 22.2

Package version

nemo 6.4.5

Frequency

Always

Bug description

When copying very large files likes ISOs to a USB progress may not be properly reported depending on the user's available RAM.

Usually one fix is to change the dirty_bytes values:

echo $((32*1024*1024)) >/proc/sys/vm/dirty_background_bytes  
echo $((1024*1024*1024)) >/proc/sys/vm/dirty_bytes

It would be good if nemo handles this visually properly.

Steps to reproduce

1. Get a big enough USB to hold a large .iso file.
2. Open nemo.
3. Copy your .iso file from your computer to the USB.
4. Observe copying progress.

Expected behavior

Nemo reports progress properly.
