Subject: Fwd: Framebuffer-Display issue. (Intel® Iris® Xe)

Hi,

I notice a regression report on Bugzilla [1]. Quoting from it:

> Hello I have been having problems for some time now with displaying any linux distribution with the new kernal. The only thing that can fix it are older kernals.
> 
> I can't describe it very well, so I'm attaching some pictures, but it's like whenever anything happens on the screen, it pushes the upper left half up from the bottom. But it only goes to a certain extent, after that it just shakes around and jumps back a bit. Also, for example, the firefox icon is not where it is displayed, but where it should be (I tried it with touch).

See Bugzilla for the full thread and attached pictures that demonstrate
this regression.

Anyway, I'm adding it to regzbot:

#regzbot introduced: v6.1..v6.4 https://bugzilla.kernel.org/show_bug.cgi?id=217666
#regzbot title: screen shakes on Intel® Iris® Xe

(also Cc'ing stable list because it also occurs on v6.1.y, but not in
v6.1 mainline).

Thanks.
