Problem Description

Whenever I copy or cut, the rdp connection seemingly hangs for a few seconds, no interaction is possible for a few seconds and the view does not change. This only occurs when using Remmina, and occurs whether clipboard syncing is on or off.

If I connect to any device via xfreerdp directly (ie. xfreerdp /u:JohnDoe /p:Pwd123! /w:1366 /h:768 /v:192.168.1.100:3389 ), this issue does not occur.

Edit: Upon further review this seems isolated to Copy/cut within visual studio instances on remove devices. This also does not occur with xfreerdp by itself, which might indicate a Remmina-related problem? Though it is very odd that I can only replicate this by copying text from a VS instance on a remote device, and only with Remmina and not XFreeRDP...

What is the expected correct behavior?

Copying should have no delay, and shouldn't hang VS
