From 63583c15db94825529f6232feca7bd4671c45db2 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 88be1f513d..b8068ecded 100644 --- a/gdk/macos/gdkmacossurface.c +++ b/gdk/macos/gdkmacossurface.c @@ -807,7 +807,7 @@ _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
