406720 - Audit all uses of window frames for resolution-independence-unsafe assumptions

Status: RESOLVED WONTFIX

(Core :: Widget: Cocoa, defect)

Description

[Stuart Morgan]

Window frame coordinate systems cannot be assumed to be the same as those of
view (and therefore Gecko) coordinates. I believe from a quick glance and my experiments with simple pop tests that the nsCocoaWindow positioning and sizing code have bugs due to this, but there may well be other places.

See

for reference, and bug 406719 for an example (in Camino) of the sort of thing this involves.

A lot has changed since this was filed, I doubt it's relevant any more.
