Will I incur an overstay if my flight leaves 15 minutes after my visa expires?

Quick question, my visa expires on 2nd.

I fly from Chiang mai to Bangkok on the 2nd in the evening where I then get my connecting flight to the UK.

The flight from Bangkok to the UK however departs at 00:15am on the 3rd. Meaning I am now in Thailand 15 minutes longer than I am allowed. Does this mean I will be given an overstay?

Or will the fact that passport control will have already stamped my passport as “departed” by the time my plane leaves be ok?

Thanks
