The default was to have enable_bg_fill disabled and the first plane set it if it wasn't opaque and covering the whole screen. However that meant that if no planes were enabled, then the background fill wasn't enabled, and would give a striped output from the uninitialised output buffer. Initialise it to enabled to avoid this.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
