From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Martin Sirringhaus Date: Mon, 25 Nov 2019 09:31:46 +0200 Subject: [PATCH] Bug 1504834 - XULText-AA-fix BE For FF68, AntiAliasing of XULTexts seem to be broken on big endian (s390x). Text and icons of the sandwich-menu to the right of the address bar, as well as plugin-windows appears transparant, which usually means unreadable (white on white). https://bugzilla.mozilla.org/show_bug.cgi?id=1504834#c9 --- gfx/skia/skia/src/opts/SkBlitMask_opts.h | 2 ++ 1 file changed, 2 insertions(+) diff --git a/gfx/skia/skia/src/opts/SkBlitMask_opts.h b/gfx/skia/skia/src/opts/SkBlitMask_opts.h index 8e673a972869c8e1cac0ed3db4aa34a9b7f4cf6b..3dcde0bb81273ee509322863285dd6d8d7a96648 100644 --- a/gfx/skia/skia/src/opts/SkBlitMask_opts.h +++ b/gfx/skia/skia/src/opts/SkBlitMask_opts.h @@ -210,6 +210,8 @@ namespace SK_OPTS_NS { // ~~~> // a = 1*aa + d(1-1*aa) = aa + d(1-aa) // c = 0*aa + d(1-1*aa) = d(1-aa) + // TODO: Check this for endian-issues! + // Do we need to switch 255 to the front for all of those tuples? return (aa & Sk4px(skvx::byte16{0,0,0,255, 0,0,0,255, 0,0,0,255, 0,0,0,255})) + d.approxMulDiv255(aa.inv()); };
