+Subject: [PATCH] Fix flickering
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+- in GR_Caret::s_blink_timeout, avoid repeated calls by stopping the
+  timer, it will be restarted when needed,
+
+- in GR_Caret::s_enable, avoid extra unnecessary _blink calls when blink
+  is enabled, as they serve no purpose,
+
+- in XAP_UnixFrameImpl::_fe::expose, use the Cairo clip rectangle
+  instead of the expose event area, thanks to Hubert Figuière in
+  865c1dda7e13deff04573ffc42028b71fee07f9c,
+
+- in XAP_UnixFrameImpl::_fe::expose, do not return FALSE, as other
+  handlers will need to handle the draw event,
+
+- in GR_UnixCairoGraphics::flush, fix excessive draw events;
+  gtk_widget_queue_draw only marks the widget as needing redrawing,
+  which causes a draw event for each call to flush, therefore every
+  caret blink, so use gdk_flush instead,
+
+Fixes AbiSource #13791.
+Fixes Debian #851052.
+Fixes Fedora #1287835.
+Fixes Ubuntu LP: #1574278.
+Fixes Sugar Labs #4915.
