[Ubuntu Linux Gnome3] X Request 31.0 BadWindow error on a regular basis

[Thibaud TOURNEUR]

Hello Citrix,

First of all, I'm not sure I'm writing to the right support. If not, could you relocate it? Thanks in advance.

I'm connecting to the company I work with through a Citrix Portal from an Ubuntu Linux PC with Gnome3 as XWindow Window Manager. On a regular basis, I get a dialog stating a bad window error (see attachment). Usually, simply cancelling makes the problem go away. Could you silence that useless dialog (self-applying the action behind the "cancel" button)? Thanks in advance.

Besides, I must say I'm always annoyed by the maximized window probe, that often gets in the way, sometimes even when there's a displayed window, which is rendered unusable due to the constant flashing and focus lock (I can't click on the underlying window, probably related...). Also, when all windows are minimized, or when the current window loses focus because a pop up opened, the probe wakes up and comes harassing around. If you could do something about it. Thanks.

Regards.
