Public bug reported:
Binary package hint: vinagre
OS : Ubuntu Karmic (patches are up-to-date)
There is a huge performance related bug in Vinagre for SSH session
terminals.
After such a session has been opened, general drawing speed is very slow
in the embedded terminal : a simple thing such as a 'top' lags
noticeably at each screen refresh. Worse, launching a command which
outputs continuously on the standard output completely blocks the X
server, which becomes unresponsive (ie. whole desktop is frozen) until
vinagre is killed. It probably means that vinagre is flooding the X
server with drawing commands ....
Connecting to the same remote servers and launching the same commands
from a "standard" gnome terminal works perfectly, and since vinagre uses
(I think) the same VTE widget, there must be something fishy going on in
vinagre itself.
There is a very interesting workaround for this bug : if the vinagre
window is unmaximised and then maximised again, the slow down completely
disappears ! The console behaves perfectly like a standard gnome
terminal after that.
In case it would be related to a graphic driver problem, it's an Intel
Q35 chipset (using the free intel driver shipped with karmic).
