problem with Emacs 25.2.1 under Mac OS 10.13 beta 5

[Artemio Gonzalez Lopez]

Hi all,

I've been using Emacs 25.2.1 (downloaded from emacsformacosx.com) with 
several developer betas of Mac OS 10.13. I had no problem until the 
latest (beta 5), which does not render properly the fringes and the 
header/mode lines in Emacs windows. More precisely, it renders them in 
solid black, which in particular makes it virtually impossible to read 
the text messages in the header/mode lines. I am attaching two png 
files, showing how a window is rendered now (Fig. 1) and how it should 
be rendered (Fig. 2). This is probably a bug in macos's CoreGraphics (in 
fact, I've filed a bug report to the effect). However, while the bug is 
fixed (I hope in the next beta release!), I thought perhaps there could 
be a way of manually setting the background color of the fringes and 
header/mode which is not overridden by macos. Any suggestion in this 
respect would be very welcome!
