@JoeCFD great!! Will start experimenting

I have since found out that grabWindow doesn’t work under Wayland. So I either have to find another way or resort to X11 again.

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.

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.
