I recently updated Corona from public release 2017.3184 to daily build 2018.3280. I noticed that in all our apps the emitters behave strange when the "camera" moves or if the object, on which the emitter is inserted, moves.
I have attached 2 videos showing the same scene, one is run with 2017.3184 (correct) and the other with 2018.3280 (wrong). The shine effect of the gold works with an emitter which is inserted in the chest display group. In the "wrong_behaviour.mov" notice how the shine particles escape the chest as if they have some kind of render delay. In the "normal_bahaviour.mov" the particles' position relative to the chest, remains the same.
A similar issue appears in all our apps and in all uses of particles. The case shown in the video is just a minor one, in some cases the effect is unacceptable.
