I don't believe X11 will allow negative coordinates, as traditional geometry uses the form AxB+C+D where the (+) can also be a (-) to cause the offset to be from the right hand side or bottom of the display. You should however be able to use coordinates that are GREATER than the visible desktop.

@payman i have no experience with accessibility on Linux. But maybe the following helps you: Qt Accessibility is based on AT-SPI via DBus on Unix/X11 and is tested to be working on Gnome and KDE. Are you sure that i3wm even supports accessibility?

Actually I have since spotted what the problem was, As it turns out creating a new instance of QNetworkAccessManager every 15 seconds is not the best idea if you're not deleting them. The solution I went with was making *manager a class member.
