1192085 - Pointer position is incorrect when drag window to screen with different DPI

Status: RESOLVED DUPLICATE of bug 1189565

(Core :: Widget: Cocoa, defect)

Description

[Xidorn Quan [:xidorn] UTC+11]

Steps to reproduce:
1. open a window in one screen
2. drag it to another screen which has a different dpi (either from lo-dpi to hi-dpi or reverse)

Expected result:
everything works fine as if the window was initially opened in the target screen

Actual result:
the scale of pointer position seems to remain in the previous screen, which makes the position of the cursor doesn't match where it interacts with the UI. e.g. when from hi-dpi to lo-dpi, you can see the I-beam for the address bar on a far lower place.

This seems to be a very recent regression. I didn't see this issue in aurora, neither in the nightly several days ago.
