Interesting that turning off driver bug workarounds fixes something. On your Mali, can you go into Tools / System Information and check the Driver Version?

Oh, and there's also the issue that the video and audio of this game's episodes are out of sync, this happens on the first playthrough.

@hrydgard

The game Silent Hill Origins has a bug with the flashlight and it stops working when entering new areas, but there is a solution which consists of making a quick save and then loading it and the flashlight works again, this bug happens in Vulkan and OpenGL

Here a video https://zippyshare.day/N8TZy4GxvbcPLmM/file

Tested on Adreno 725,
