Screen tearing Intel i915 Kernel 5.9 and 5.10

[Bankman]

using kernel 5.9 or 5.10 makes the display of my Acer ES15 unreadable.

   inxi -G
  Graphics:
  Device-1: Intel HD Graphics 620 driver: i915 v: kernel 
  Device-2: Chicony VGA Webcam type: USB driver: uvcvideo 
  Display: x11 server: X.Org 1.20.10 driver: intel unloaded: modesetting 
  resolution: 1920x1080~60Hz 
  OpenGL: renderer: Mesa Intel HD Graphics 620 (KBL GT2) v: 4.6 Mesa 20.3.1 

with Kernel 5.4 or 5.8 it works norml:

Is there any solution for this problem?
thx

Wow, that looks ugly It’s not screen tearing though.

Anyways, you could try it with the modesetting rather then the intel driver.
Just remove xf86-video-intel package.

Removing xf86-video-intel caused a blackscreen. Had to chroot into my system to repair it.

Woops. Was switching to tty not even working?

Maybe you have a xorg config file left like:

/etc/X11/xorg.conf.d/20-intel.conf

Which would need to be removed also (or better rename to .bak)

Thanks a lot @moson !
Now it works
