I can see the brightness gradually gets higher if I open a white window. In fact, the change is not very smooth, so that I can obviously feel the many gradual changes, which are annoying.
It was not like this before, but it suddenly started acting like this recently. I have updated the laptop to the latest BIOS and drivers.
I have searched the web, and this can be disabled in Intel's graphics settings. But I cannot find such an option. My IGPU is Intel HD Graphics 620. Is there any way to disable this without using Intel's Graphics settings like editing Windows Registry or something?
I have checked the advanced power settings, and it had already been 'off'.
This is generally called adaptive brightness, and it sometimes needs the manufacturer’s support to modify if it’s a setting built into the display firmware itself. For example, see this recent forum thread for the Dell XPS laptop, where Dell has published a firmware update to disable adaptive brightness on laptops with 4K screens, but not laptops with 1080p screens.

Try looking through the BIOS settings, and try contacting your laptop’s manufacturer to see if they have released a custom firmware to disable adaptive brightness. You could also try downgrading your BIOS and drivers to older versions (the versions that worked before), but there could be security implications if the latest BIOS has security patches and new Intel microcode.
