xinerama window mapping bug

[kristopolous]

with the xinerama feature on and specifically with the geometry that I'm using it with (2 same model, portrait mode (rotated) screens, equal resolution, at 1200x1600 creating a 2400x1600 desktop between them) and using the window floating mode, there are a number of mapping issues on the right-hand (furthest from the 0x0 point) screen.

For instance, changing the font of an xterm window (right clicking, choosing a vt font) will move the terminal window off screen as opposed to respecting the top/left offset after the change.

Also some application dialog windows get open into windows that cannot be accessed.

It is not always clear whether this is a Notion problem or a problem with the app - some apps get confused when their windows have the WScreen as a parent instead of the root window IIRC. I'm fine with keeping this issue open as a 'parent issue', but we should probably make separate issues of specific instances of this problem, as they might have different solutions.

For instance, changing the font of an xterm window

I can reproduce that, interesting. Perhaps good to create a separate issue for that particular case?
