This is the root cause of the non-deterministic behavior of light baking. The shadow system was not given enough update iteration to fully render all tiles of the Virtual shadow maps. This would resulte in missing tiles inside the bakes. The value of the tiles seems to have been implementation dependant, which, on some implementation created light leaks. This fixes some recent regressions on the MacOS builbot tests. This is candidate for backporting to 4.2. Fix #138147 Pull Request: https://projects.blender.org/blender/blender/pulls/138203
