Furthermore, the tooltip frame isn't supposed to move once it is
displayed, AFAIK.

I'll commit the patch soon, but the bug will remain open until I check
the MS Windows case. The test on Windows I mentioned at the beginning of
this issue was not valid, because it used only monitor. It is frequent
to connect MS Windows laptops to an external monitor and use both
displays, effectively duplicating the setup I have on GNU/Linux: two
monitors with different resolutions.
