Citrix windows are lost during virtual desktop change if desktop flip animation is enabled

[mcalamelli]

The title pretty much says it all.

Steps to reproduce:

1. Enable desktop flip animation
2. Open a Citrix metaframe presentation server window (I am using the firefox

citrix ICA plugin)

3. change desktop
4. Go back to desktop which contains the citrix window.
5. Window is lost.

Always reproducible.

Turning off the desktop flip animation fixes this problem. Using window locks does not remedy the situation. The only workaround is to disable the desktop flip animation.

This may in fact be a Citrix problem, but I thought I would bring it to your attention.

The windows is not lost, it's basically out of the display. Doing a xwininfo on the window-id will tell you where that windows is. I used to run something like "while xdotool windowmove <WIN-ID> 0 0; sleep 3; done" as a workaround.

Definitely a Citrix ICA client problem. On a laggy connection, we can see than when we move the citrix window with the mouse, it's not smooth, like the windows is trying to set its position from coordinates given by the server as we move the window. Also, this problem is much less reproducible when i am next to the citrix server box.

So basically, the problem is that the client detect a window move to -1280, ask the server about it, and when the server responds, it tells the client to set the position to -1280. On a laggy connection, the flip animation is faster than the request.
