@Alumx , guess issue is not render engine specific . Try render mode cycles/Eevee and change state/properties of mesh (eg. switch to material preview then change mesh color ), Same result you will get (vibration) . Though not sure , someone else can confirm the issue .

Tested on Blender version : 2.93.0 Alpha , Hash : 0bc281a6dd1 (commit date : 2021-02-14)

The issue seems to be the first AA sample is incorrectly offset, if you turn up the filter size very high there's an obvious outlier (in the top right):

The same image but with exactly 1 sample:

The same image but solid view

These were taken with a filter size of 250px, which is obviously way beyond any realistic value but it makes the cause of the wobble a lot easier to see :)
