#25 switching to gnome-terminal from a windows application selects a whole line of text clearing the clipboard

[Swizzly]

Hi,

Switching focus from outside of the x-session (i.e. from a windows application) by clicking with the left mouse button into a gnome-terminal window inside the x-session a whole line of text get selected/highlighted, that also cleans out the content of the clipboard...
Switching from an other linux applications/window (i.e. from inside the x-session) to the gnome-terminal window doesn't have this issue.
Using other x-server application like Opentext Exceed, the problem doesn't occur.

I analysed with xev the x-events:

It seems vcxsrv adds an additional MotionNotify event between the ButtonPress and ButtonRelease events, which triggers the line selection in gnome-terminal.

Question: why does this happen, how can it be resolved?

It seems the problem occurs with RHEL v6.5 distro, that comes with Gnome 2, gnome-terminal v2.31.3., xorg v7.0.0. I made some short tests on RHEL v7.1 and it wasn't influenced by the issue.
