Yes I changed the code but the problem is still there. Is there a ResizeObserver in the code somewhere? If you can tell me, where it is, it might point me in the right direction as to what might be happening? Like I said before, I have an event search which is outside of the main scheduler. And when I search, I set the inlineData.events again, and that is 10k+ events sometimes. It seems to work the first time when the scheduler loads. The problem is only when I reset the inlineData.

It's not the events I am filtering....it's actually the resources I am filtering. So, e.g. at first, I have 200 resources with 50-70 events each and then after a search, I might have 50 resources left. The search is done on a local IndexedDb database and search is performed on several fields which are not part of the ResourceModel or EventModel. Any suggestions ?

I just tried filtering the resources (instead of resetting the inlineData) and I still get the same ResizeObserver issue.

  useEffect(() => {
    const schedulerInstance = multiSchedulerRef.current?.instance;
if (!schedulerInstance) {
  return;
if (searchType === 'person' && searchCriteria?.key === 'displayCode' && searchCriteria?.value) {
  const resourceStore = schedulerInstance.resourceStore;
  resourceStore.filter({
    filters: [{ property: 'display_code', value: searchCriteria.value, caseSensitive: false, operator: '=' }],
  }, [searchType, searchCriteria]);
