Does this problem occur in fluxgate compasses also?


No.
OTOH, you should not rely on a fallible electronic device
as your only compass.

Redundancy is good. Autopilot compass is flux gate (plus NMEA GPS
input), Richie bulkhead mounted standard compass, Davis hand bearing
compass, Wheams flux gate hand bearing compass, and compass in binoculars.
