Confirmed.
Guillaume, it’s the FileMonitor which is detecting the file save as external
modification.
How can I provide further info to correct this annoying behavior?
My attempt to diagnose the culprit failed - the code is too weird for me :(
I tried to stop in Buffer::Impl::refreshFileMonitor() at the first line.
The debugger didn’t stop - but it stopped in
Buffer::Impl::fileExternallyModified()
and the call stack claims it comes from the last line in refreshFileMonitor()
???
Frankly said: I’m lost now.
