Is this normal? Please help 😔

Is it normal that after not using it for a few hours, the screen of my MacBook Air m3 sticks to the bottom part of it?

For that and another problem I already sent my MacBook to apple for a repair. They changed the Display part and the problem wasn't there for a few days. Then, it occurred again (sometimes I think even stronger than before). Should I send it in again? (Not really want to because I need it and it would get shipped to Czech Republic, so far away) Could that damage the MacBook over a longer time? How can I prevent this from happening? Please help!
