When a window is shown, it may not have drawn its content into the backing
surface, yet. Cocoa will draw the window, starting with its standard light
gray background and then the content view. However, the content view won't
have anything to draw, yet, though, so the window background is not drawn over.
A short while later, usually, the app will paint its content into the window
backing surface and Cocoa will be told to redraw the window. This works, but
the user can often see the flash of the window background color first. This
is especially visible for windows with dark content.
Part of the fix is to set the window background to transparent until the
content view has actually drawn once since the window was shown.
That's not sufficient on its own, though. We had disabled Cocoa's automatic
display mechanism for windows and put display on a display-link timer. This
meant that the window was not actually cleared to its transparent color. When
the window was shown, the Window Server displayed a white backing buffer. It
is the app process which should fill that backing buffer with clear color but,
because we had disabled auto-display, that wasn't getting done at the same
time the window was displayed. It was happening some time after. Again, the
result was a visible flicker of white.
So, we now temporarily re-enable auto-display just before showing a window.

This avoids a Cocoa bug where, if an app in the background which is not
hidden calls -unhide:, its main menu bar window is brought forward. The
active app hasn't actually been changed. Key events continue to go to
the app in the foreground. But it's confusing to the user when they
look at the menu bar and, if they click in the menu bar, the background
app really will be activated.

This only really affects OpenGL child windows. GDI rendering to the window
surface is still only blitted to the window's content view. The descendant
views don't draw and so are transparent, letting the content view show through.
Using Cocoa views for child windows fixes a problem where changes to the
position and visibility of child GL windows didn't properly affect the Cocoa GL
view. Hiding, showing, and moving the top-level window affected the Cocoa
window and thus, indirectly, the GL view. Moving the child GL window itself
was propagated to the GL view, so that worked. But hiding, showing, or moving
any of the intervening ancestors of the child GL window didn't properly affect
the GL view. Neither did hiding or showing the child GL window itself.
This also slightly improves the clipping of the GL view by its ancestors,
although it still doesn't work quite right due to Cocoa bugs. There are also
remaining bugs with z-order among multiple GL views and clipping by overlapping
siblings. I hope to eventually fix those using Core Animation layers, for
which this is a prerequisite.

When this Retina mode is enabled and the primary display is in the user's
default configuration, Wine gets told that screen and window sizes and mouse
coordinates are twice what Cocoa reports them as in its virtual coordinate
system ("points"). The Windows apps then renders at that high resolution and
the Mac driver blits it to screen. If the screen is actually a Retina display
in a high-DPI mode, then this extra detail will be preserved. Otherwise, the
rendering will be downsampled and blurry.
This is intended to be combined with increasing the Windows DPI, as via winecfg.
If that is doubled to 192, then, in theory, graphical elements will remain the
same visual size on screen but be rendered with finer detail. Unfortunately,
many Windows programs don't correctly handle non-standard DPI so the results
are not always perfect.
The registry setting to enable Retina mode is:
[HKEY_CURRENT_USER\Software\Wine\Mac Driver]
"RetinaMode"="y"
Note that this setting is not looked for in the AppDefaults\<exe name> key
because it doesn't make sense for only some processes in a Wine session to see
the high-resolution sizes and coordinates.

Cocoa manages an autorelease pool on the main thread, but it only drains it
when it processes an event. Our requests come through a run loop source, which
doesn't count as an event. So, autoreleased objects can accumulate when the

Most queries are handled even by threads which are otherwise blocked in
OnMainThread(). There's a problem with QUERY_IME_CHAR_RECT, though, in that it
can be handled before a previously-queued IM_SET_TEXT event, in which case its

The change to a CVDisplayLink-driven display mechanism introduced a problem: a
Wine process never went completely idle for long periods. The display link
would fire for every refresh cycle of the display, waking a CPU from idle and
wasting energy.
To fix that, I have the display link stop itself when it determines that none
of its windows need to be displayed. When a window is subsequently marked as
needing display, it either temporarily re-enables Cocoa's normal autodisplay
mechanism so that it displays at the end of the current turn of the run loop,
or it restarts the display link. It chooses the former if it's been a long
time since the window was last displayed so that the display is done more
immediately.

and later.

Some Windows apps cause user32 to flush the window surface much faster than the
display refresh rate. The Mac driver only marks its window as needing to be
redrawn and lets Cocoa decide how often to actually redraw. Unfortunately,
Cocoa redraws each time through the run loop and, since the Mac driver uses a
run loop source to convey messages from background threads to the main thread,
it redraws after every batch of messages.
On some versions of OS X, this excessive drawing provokes synchronization with
the window server's buffer swaps, preventing the main thread from being
responsive. Even when that doesn't happen, it's wasteful.
So, we set our windows' autodisplay property to false so that Cocoa never
displays windows itself. Then, we arrange to call -displayIfNeeded once per
display refresh cycle using a CVDisplayLink. We maintain one CVDisplayLink per
display (on demand), move windows among them as the windows change screens,
start them when they acquire their first window, and stop them when they have
none left.
