Description Pierre Ossman cendio 2018-06-15 14:54:29 CEST
We currently have some issues dealing with very large clipboard requests:

a) The server has a limit on incoming clipboard (MaxCutText). By default it is set to 256 KiB.

b) Most applications want to use the INCR protocol for anything more than 256 KiB. We support this in the client, but not the server. Most applications will still accept incoming clipboard even without INCR. In that case we start running in to problems when we approach the maximum request size (16 MiB) instead.

c) noVNC has crash bugs on both incoming and outgoing large clipboard. Fixed upstream though:

There is now an issue upstream for INCR support:
