<p dir="auto">The problem seems to be that when linking with the 10.14
SDK, views will draw into their own separate layers, so we can no longer
“erase” the background with <code style="background-color:#F7F7F7;
border-radius:3px; margin:0; padding:0 0.4em" bgcolor="#F7F7F7">NSColor.clearColor</code>
to make a subset of the window transparent (as we no longer erase into
the shared buffer for enture full window).</p>
<p dir="auto">Instead we must ensure that all ancestor views are
transparent, which would include setting <code
style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0
0.4em" bgcolor="#F7F7F7">backgroundColor</code> to <code
style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0
0.4em" bgcolor="#F7F7F7">NSColor.clearColor</code> for our window, and
then making sure that all other views in the window have an opaque
background.</p>
<p dir="auto">It might be doable, but a quick test showed a problem with
the file browser, as it is using an <code
style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0
0.4em" bgcolor="#F7F7F7">NSVisualEffectView</code>. It might work if we
put a view behind the <code style="background-color:#F7F7F7;
border-radius:3px; margin:0; padding:0 0.4em" bgcolor="#F7F7F7">NSVisualEffectView</code>
to draw the window background, but I’m hesitant to pursue this, as the
less assumptions we make about how these views work, the better.</p>
<p dir="auto">There is the ability to use an <code
style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0
0.4em" bgcolor="#F7F7F7">NSVisualEffectView</code> behind the text view,
but that would be a different kind of transparency, unlikely to be
compatible with the themes currently using alpha.</p>
