You need a qualified technician to inspect and service it. It is possible the air shutter is open too far from the looks of that flame. Also note how centered the flame is--poor lateral distribution. A tech can inspect the settings, orifices, gas pressures, etc. and ensure it is setup and operating within mfrs. specs.

For a home inspector, yes, it would be a trigger for a tech.

Heating appliances use a clean burning 'non-luminous' flame whereas most hearth appliances rely on a luminous flame and therefore are inherently a little less efficient and a little more dirtyas Gene and John point out. The standard flame has blue bases with yellow tips, even distribution across the burner with no lifting or ghosting.

Good points guys!
