Rendering réalistic quality on walls decreased

Hello
In the version 2.9, i noticed something weird in the rendering quality, less realistic.
In each intersection between walls / ceiling, or walls / walls, there is a marked dark line that didn’t exist in old versions. Those lines are really no natural…
here is a comparaison between old version of D5 and 2.9.
