Please note that 6.4.1 isn't particularly new.
"Between 6.4.1 and the current 6.4.2 more than 770 updates have been applied."
"Over 830 new features and bug-fixes have been applied since 6.4.2. "

A remark: The current resolution is hence 1-2cm given that you are in UTM?
BTW: You may consider to check if you do not want to have square
pixels (and if so, why they aren't).
