Window repositions after clicking "install ubuntu"

[Nathan Teodosio]

I'm testing on safe graphics, but probably this is not specific to it.

Reposition the Ubiquity window, then click "Install Ubuntu".

Expected: Keyboard layout page comes up, window stays in place.

Observed: Keyboard layout page comes up, window repositions to the center of the screen.

Thank you for taking the time to report this bug and helping to make Ubuntu better. I could reproduce this behavior with the Ubuntu 22.04 ISO in a QEMU VM:
* Boot installer ISO
* Move install window
* Click on a language. The windows jumps to the center.
* Move install window
* Click "Install Ubuntu". The windows jumps to the center.

Why do want the window to stay in place? Is it a problem that the window repositions to the center of the screen?

As I was testing in Qemu and with safe graphics, I was only able to see
about one quarter of the whole screen, so I dragged it to that quarter
and expected it would stick there throughout the installation.

Of course that could be adjusted by zooming out.

A window that repositions itself is never a real blocker — at most an
annoyance —, but this being Ubuntu's installer, a.k.a. the first
impression for new users, I believe it has to be nitpicky about
reliability and consistency.
