Ok, I can confirm that drop of this patch is fairly safe, because upstream of tigervnc applied b5822f32ab5043b4e70e55ccbac0f548a2f784fc commit to fix (work-around zlib) issue. Reverting this patch in EPEL7 leads to tigervnc-server failure (similarly on Fedora) with reproducer: server $ vncserver # starts on :2 client $ vncviewer CompressLevel=2 server:2 with the following server log: Xvnc TigerVNC 1.3.1 - built Jan 29 2017 15:56:11 Copyright (C) 1999-2011 TigerVNC Team and many others (see README.txt) See http://www.tigervnc.org for information on TigerVNC.
