Client disconnects on mouse entering screen when server clipboard big.

[Stéphane Gourichon]

## Context

Using synergy with an Ubuntu 12.04 client and a Windows 7 server connected over wifi. Works like a charm for hours.

## Action

Pressed "PrintScreen" key. Server clipboard now contains 8MB of data (1920x1080 32-bit screen data).

## Expected

Continued execution

## Observed

Every time I move the mouse to the Ubuntu client screen : on Ubuntu client screen, pointer jumps correctly to edge then stays stuck there, or even disappears. Local mouse still works.
Problem be repeated at will.

## Workaround

Flush clipboard by

Client believes server is dead, server does not actually look so.

At that point, on the server I select and copy a small text to flush the clipboard.

After that everything works fine.

Trying to link with upstream bug as of https://wiki.ubuntu.com/Bugs/HowToTriage#Forwarding_upstream

Launchpad says synergy uses bug tracker at Sourceforge.net.

Launchpad rejects URL http://synergy-foss.org/tracker/issues/138 "Launchpad does not recognize the bug tracker at this URL."

So, marking as known upstream without URL.
