From e3ef21f77033a7a92d63e55c3dc7c987faa4fcf0 Mon Sep 17 00:00:00 2001 From: Christian Hergert Date: Thu, 14 Oct 2021 14:46:30 -0700 Subject: [PATCH] macos: fix scale on macOS 12 beta This is a port of the fix in the quartz backend to the new macOS backend. From the original commit: In macOS-12.sdk CGContextConverSizeToDeviceSpace returns a negative height and passing that to CGContextScaleCTM in turn causes the cairo surface to draw outside the window where it can't be seen. Passing the absolute values of the scale factors fixes the display on macOS 12 without affecting earlier macOS versions. --- gdk/macos/gdkmacossurface.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/gdk/macos/gdkmacossurface.c b/gdk/macos/gdkmacossurface.c index f94eaa2eca..60f6fe2389 100644 --- a/gdk/macos/gdkmacossurface.c +++ b/gdk/macos/gdkmacossurface.c @@ -809,7 +809,7 @@ _gdk_macos_surface_acquire_context (GdkMacosSurface *self, scale = CGSizeMake (1.0, 1.0); scale = CGContextConvertSizeToDeviceSpace (cg_context, scale); - CGContextScaleCTM (cg_context, 1.0 / scale.width, 1.0 / scale.height); + CGContextScaleCTM (cg_context, 1.0 / fabs (scale.width), 1.0 / fabs (scale.height)); } return cg_context; -- 2.30.2
