Intel HD Graphics 5500: Image runs off screen, rendering errors

I set up a ThinkPad T550, and the included Intel HD Graphics 5500 graphics (Broadwell-U) is quite unstable. Some issues:

• Sometimes when exiting from X11, started with startx, on the console the image runs to the left side off screen, and comes back in on the right side, continuously.

• Sometimes after resuming from suspend for RAM, parts of the screen are not properly updated. Screenshot, after trying to fix the rendering by moving around windows (made it worse):

Any idea how to fix these issues?

During boot, I get the i915 module loaded, to be able to activate a larger font size right from the beginning: It's a 3K 15.5" screen.

Just let the image run for a few minutes, and - surprisingly - then it stopped.

It almost looks like a CRT which lost synchronization: weird problem

Re: Intel HD Graphics 5500: Image runs off screen, rendering errors

Something else that I tried is enabling tear-free video in /etc/X11/xorg.conf.d/20-intel.conf:

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "TearFree"    "true"
EndSection

This indeed seems to improve video playback and scrolling, which is nice. However, if it doesn't prevent the issue with the running image after shutting down X. I then restarted the machine, adding as kernel parameter: i915.semaphores=1

Again, this didn't help.

Any other ideas?

I can confirm the 'running image' problem (same card, Asus 303la). The perplexing thing is it only seems to happen some of the time. Sometimes if I switch to a tty from X it'll be happening, but then it'll stop, sometimes when I switch/shutdown it's not there at all. Must be doing it periodically I suppose?

I'm on linux 4.0 from testing, will let you know if anything I do works.

Same here, and sometimes it doesn't stop, or maybe I would have to wait for a very long time.

Our machine is still on 3.19. I was hoping that upgrading to 4.0 solves the problem.

Yeah, at first I thought maybe it was regular, but it seems random, sometimes it doesn't stop.

Yup. I might try to file a bug with Intel/mesa later.

Curiously enough, the 'running image' problem stops if you switch to a Wayland display. Perhaps not the best workaround, but at least it's something.

It does seem like it only ever happens when switching from X11 to a tty though.

(I'm using gdm.)

Also affected by this, same card on a ThinkPad X1 Carbon.

The Tear-Free Video thing seemed to make the tearing less intense, but it's still very much occuring.

Also happens when I log out from Cinnamon to LightDM (so not only when switching to console).

EDIT: So, after having searched far and wide, I found this wiki page which provided a solution. Passing the kernel parameter

i915.enable_ips=0

at boot worked for me (disabling SNA as per this wiki post also works, but seems like a worse solution).

That's almost definitely a completely different issue, and not an issue with Intel graphics.

IIRC its fine when i'm running on the nvidia gpu and only occurs on the intel.
