The tick interrupt is configured using the library provided by ST. See the function prvSetupTimerInterrupt() in port.c. The existing code I think uses the library incorrectly. Unfortunately this is also the case in V4.0.0 to be released tomorrow. This is the only "known issue" in V4.0.0 and will be on the issue list tomorrow.
Take a look at the function, as it uses the library it should be simply to fix (I hope), unless the library itself is incorrect.
I have seen 1000Hz works ok, but 100Hz, not so can confirm your results. Sorry for inconvenience!
