Flickering caused by Intel HD Graphics?

[REspi3]

I just bought an Asus X454LD a few days back with a little issue.

Originally purchased it last 5/5/15 and after a day of use the screen started to flicker all of a sudden. There are no specific times or programs that could trigger this flicker, it just happens. I assumed it's a hardware defect or something like that.

So 5 days after the purchase, I went back to the Asus store were I originally got it and they immediately replaced it. As I got home and did some updates, the flicker is still there! So I'm suspecting that the problem that causes this is software. The laptop does come along with a discrete GPU (820m) but I believe what's running the actual display is the Intel HD graphics (4400) and it will just be switched to the discrete GPU if necessary. I have provided a picture and a video so you can see it for yourself.

Note: This was a part of a 20min long video I took just to get a shot of the problem (oh, and the video is slowed in speed)

Picture: (notice the desktop wallpaper)

Hi Ryuuichi

You mentioned that the issue started occurring after you did some updates? Specifically what updates did you do?

Thanks

Just some Windows Updates, and removed some bundled software from the OEM. But that was the first unit before it got replaced. The new replacement unit showed the problem already minutes after it was first turned on, no updates whatsoever.

Hi Ryuuichi

Because the ASUS X454LD is a Hybrid Graphics system I would strongly recommend only using the graphics drivers provided by ASUS on the system here: http://www.asus.com/us/supportonly/X454LD/HelpDesk_Download/ ASUS USA

Uninstall all existing graphics drivers , both Intel and NVidia, then reboot. When the system has rebooted, first install the ASUS supplied Intel HD Graphics driver. Reboot the system, then install the ASUS supplied NVidia graphics driver.

Thanks

I have reinstalled both drivers. Now I'll have to wait and see. I'll let you know if it fixed the problem. Thanks!

Edit: It's still there

Hi Ryuuichi

Is this a new system still under warrantee? If so, you may want to work the issue with ASUS or the Place of purchase.

Thanks

It is possible that this message you are getting during the installation is caused by the Driver signature so please follow these steps:
