[Intel Gemini Lake] White lines flickering at top of the screen

Greetings everyone,

I recently bought a new laptop, an Acer Swift 1 SF114-32.

CPU : Intel Pentium N5000 (Gemini Lake) iGPU : Intel UHD 605

With GNU/Linux (in my case Fedora 29 MATE), I'm experiencing black/white lines flickering at top of the screen.

Here is a link of what I posted (photos mainly) :

It is not an hardware malfunction (Screen or hardware) :

  • No issue at all with WIndows 10 1809, everything is smooth and OK

It is not related to the Distro

  • The same problem occurs on Ubuntu MATE, Linux Mint MATE and Fedora MATE, even with LxQT

Other people are concerned :

One of them is also using a Gemini Lake Intel processor (Ezbook x4).

Here is my inxi -G output :

Device-1: Intel UHD Graphics 605 driver: i915 v: kernel 
Display: x11 server: Fedora Project 1.20.4 driver: intel 
resolution: 1920x1080~60Hz 
OpenGL: renderer: Mesa DRI Intel UHD Graphics 605 (Geminilake) 
v: 4.5 Mesa 18.3.6

And here the xrandr output :

VIRTUAL1 disconnected (normal left inverted right x axis y axis)

As my laptop works perfectly with WIndows 10 Home 1809, the problem is on the GNU/Linux side.

=> So, my guess would be that there is a problem either with the Intel Gemini Lake driver and/or xrandr

I would be grateful if someone could help me solve this issue :smiley:
