Lighting issue

Hi everyone,

since the 4.12 update I’ve got a strange lighting issue. With the exact same parameters, when I build the lighting of my scene, the result differs randomly.
Here are 2 views :

98684-seat1.jpg
98684-seat1.jpg1123×1056 117 KB

98685-seat2.jpg
98685-seat2.jpg1123×1040 96.2 KB

Between both views I only re-build the lighting.
Do you already encountered such an issue ?

Btw on the first pic there are strange shadows artefacts (not due to ambiant occlusion nor lightmass resolution settings), any idea how to correct this ? However the result in the second pic looks much better (but dark, what I could change).

Thanks a lot.

After more experimentation I’ve noticed that after the lighting build, it alwats appears like on the second pic for a few moment, and changes -or not- to the first one after clicking/saving. Does anybody knows why ?
