From 207f328afc2137d422f59293ba37b8be5d3e1617 Mon Sep 17 00:00:00 2001 From: Corentin Chary Date: Fri, 4 Feb 2011 09:06:03 +0100 Subject: [PATCH] vnc: fix lossy rect refreshing The for loop in send_lossy_rect was totally wrong, and we can't call vnc_set_bits() because it does not really do what it should. Use vnc_set_bit() directly instead.
