Describe the bug
When the compute setting is changed to CPU Compute, the lighting inside certain buildings acts abnormally. Rooms that should have sunlight coming through the windows become completely dark.
Switching the setting back to Auto resolves the issue, and the lighting returns to normal. However, since some devices rely on CPU Compute to run smoothly, this remains a significant issue for players who need to use that setting.
Steps To Reproduce
Go to Options and change the compute setting to CPU Compute.
Enter a building with windows during daytime (e.g., a lighthouse).
Observe that the interior is completely dark.
Change the setting back to Auto and observe that the light through the windows works properly again.
