Well, that is expected, as the issue has nothing to do with your
program, it's the caching of the operating system that is responsible
for the actual physical write to the disk.
I see something similar with some text files that I use while doing some
cross-platform work that I am doing recently.
The actual test file is on a Windows 8.1 machine, while most of the
access to that file is from either a Windows 10 laptop or a macOS Sierra
MacBook Pro. Occasionally, more pronounced when one of these two
machines is connected via WiFi instead of wired connection (on the same
logical subnet though!), when reloading the file from disk, it shows up
corrupted on the other machine, while it shows perfectly fine on the one
that did the last write. Force a new write and in 99.9% of all cases, it
will show up just fine on another reload...
Any chance that the file(s) you are working with are on a shared drive?
