My StackOverflow question on this issue

[richelbilderbeek]

Here is something to try.

[richelbilderbeek]

With aa6f1573694ed397252f11e3ab55264b32ebc361 I got this:

This looks like an improvement:

$ wmctrl -m

Name: Metacity
Class: N/A
PID: N/A
Window manager's "showing the desktop" mode: N/A
The command "wmctrl -m" exited with 0.

Also these:

$ DISPLAY=:99; wmctrl -l

0x00800003  0 testing-gce-5c0b2b54-b2df-4391-91d0-765ef5ac7787 (Untitled)
The command "DISPLAY=:99; wmctrl -l" exited with 0.

0.01s$ DISPLAY=:99.0; wmctrl -l

0x00800003  0 testing-gce-5c0b2b54-b2df-4391-91d0-765ef5ac7787 (Untitled)
** (gedit:20340): WARNING **: Could not load theme icon gtk-home: Icon 'gtk-home' not present in theme
The command "DISPLAY=:99.0; wmctrl -l" exited with 0.```

I am willing to offer a bounty to solve this problem.

This is a reproduction of the problem:

Build the testing application:

cd minimal_project
qmake
make

Running the tests:

./minimal_project.sh 

On my local computer this is:

Starting the application
Check if the dialog can be found
Close the dialog using ALT-F4
0
Starting the application again
Close the dialog by setting the mouse at the closing glyph and clicking

On Travis CI this is:

Starting the application

Close the dialog using ALT-F4

The problem is that minimal_application is not closed by the mouse button. I will add a better test to detect this more clearly for my collaborators.
