Comment 1 Andrej Nemec 2019-01-31 13:44:13 UTC 
Created freerdp tracking bugs for this issue:

Affects: epel-6 [bug 1671370]
Comment 3 Riccardo Schirone 2019-02-18 16:41:12 UTC 
Statement:

This issue did not affect the versions of freerdp as shipped with Red Hat Enterprise Linux 6 and 7 as they did not include support for ZGFX data compression.
