Moving window from/to retina display doesn't send window_resized message (DEF-2843)

[britzl]

Description:
When moving the window between a retina display and a non-retina display on os x it doesn't signal the game with a window_resized message, which can result in rendering/position bugs.

Steps to reproduce:
Enable high dpi in game.project
add print on render script window_resized message
move window between retina and non retina screen

Expected result:
window_resized message sent to render script, containing the new resolution

Actual result:
Nothing.

I have this issue too. Also gui.pick_node() works wrong after moving a window from retina to non-retina display vice-versa. Very annoying.

I also have a MacBook with a second regular monitor. And this bug is also reproduced.
After resizing the window on another monitor, the problem goes away.
I checked the behavior on Window 10 on regular monitors - everything is fine, the bug does not reproduce.

This seems to occur even without High DPI enabled, e.g. in the defold-input example

Will migrating to GLFW3 possibly address this?

Not sure, but GLFW3 brings with it a lot of changes so it is not unlikely that it will help!
