Description

Hello, when I use guacd to connect to my host through RDP, everything is fine, but when I copy a piece of SQL text from my local computer and perform a paste operation on the remote host, the remote host gets stuck and automatically interrupts the connection, I don't know what happened, when I used mstsc.exe to connect to the same remote host, the paste behavior is normal, don't know if this is a problem with guacd? Thanks

guacd version: docker-v1.4.0
