Comment (by diwu1989@…):

 I filed ticket on FreeRDP on github
 https://github.com/FreeRDP/FreeRDP/issues/2545
 and it seems the problem is fixed in the stable-1.1 branch
 https://github.com/FreeRDP/FreeRDP/commits/stable-1.1

 I'm not familiar with the portfile system, would you be able to update the
 portfile to use the stable 1.1 sourcecode instead of the beta?
