The Qutebrowser web browser crashes after a while with the following error
message:

> intel_do_flush_locked failed: Invalid argument

If I restart Qutebrowser afterwards I obtain some sort of graphical corruption.

This only happens with 4.14.x kernels. No problem with 4.13.x kernels.

I'm running Gentoo Linux (~amd64) on a desktop machine with an Intel GPU:

> # lspci | grep VGA
> 00:02.0 VGA compatible controller: Intel Corporation 82Q35 Express Integrated
> Graphics Controller (rev 02)

Packages:
- www-client/qutebrowser-1.0.4
- x11-apps/mesa-progs-8.3.0
- x11-drivers/xf86-video-intel-2.99.917_p20171018
- x11-libs/libdrm-2.4.88

This is the result of my first attempt at bisecting a kernel:
