Public bug reported:
On an intermittent basis, Remmina will, if clipboard sync is on, drop to
an unusably low framerate after login to the remote machine. I have not
managed to fully determine the conditions under which this occurs: it
appears to happen or not happen consistently across a login session on
the local machine (conditional upon clipboard sync being on), or
possibly across a boot of the local machine. I have noticed it start
occurring or stop occurring on reboots. When it occurs, it occurs for
both remote machines I have set up (A Raspberry Pi 2 running Ubuntu Mate
18.04 and an x86 server running Debian Bullseye with LxQT). When it does
not occur, it does not occur for either machine (this seems to include
the case where clipboard sync has been turned off for one remote machine
and not the other and the connections are open simultaneously, in which
case the issue appears on neither!).
The local machine is running Kubuntu 20.04, though some Mate components
are also running on top of KDE. The connection is made via RDP, to xrdp
v 0.6.x on the Raspberry Pi and xrdp 0.9.12 on the x86 server. All
devices are in the same room, with gigabit ethernet connections. I have
verified that I am getting gigabit bandwidth with iperf3, and ping
latencies are sub-millisecond.
Remmina is version 1.4.2+dfsg-1ubuntu1
