--- Comment #4 from Urs Fleisch <urs_fleisch@yahoo.de> ---
I have probably the same problem with a HP Compaq dc7800p Small Form Factor
having Intel Corporation 82Q35 Express Integrated Graphics Controller (Intel
GMA 3100 graphics, Mesa DRI Intel(R) Q35, OpenGL 2.1, DRI driver: i915).

The problem appeared since Arch Linux switched to kernel 4.14 (but not with the
4.9 LTS kernel), I have also reproduced it on Ubuntu using mainline kernels
(http://kernel.ubuntu.com/~kernel-ppa/mainline). The problems do not appear
with 4.13.16-041316, but starting with 4.14.0-041400rc1, 4.14.0-041400-generic,
4.14.12-041412-generic, and also with the latest kernel available there
4.15.0-041500rc6-generic the problem still exists.

The easiest way to reproduce the problem is starting Chromium and going to
maps.google.com. On Arch Linux (both with KDE and LxQt) the address bar
disappears and the map tiles are totally distorted. On Ubuntu 17.10 (Gnome),
the address bar disappears as soon as I start Chromium, but the contents of
Google Maps is not distorted. On both distributions, I can see 

(EE) intel(0): Failed to submit rendering commands (Invalid argument),
disabling acceleration.

in /var/log/Xorg.0.log (Arch) or in journalctl (Ubuntu). In journalctl, there
is also the following log entry

intel_do_flush_locked failed: Invalid argument

I have looked into the kernel source of the current Arch Linux kernel
(4.14.12-1-ARCH), the commit 1d033b mentioned above is included.

With chrome://gpu, some messages are displayed

GpuProcessHostUIShim: The GPU process exited with code 256.

...a lot more of these

Please let me know if I can provide more information.
