Ah, duplicate of issue 804, sorry.

Copy paste of duplicate bug report 0002090: Windows desktop interface scaling breaks mouse pointer in menus and inventory

Description Running DayZ on a Macbook Pro with retina display (using bootcamp tom run windows).

I usually run my macbook with very large amounts of UI scaling on windows (i.e. 200%) due to the very high native display resolution (2880x1800). However this breaks the mouse on the menu systems (and inventory) - the mouse pointer does not display unless I click (right or left click) which makes the mouse pointer appear; if I move the mouse it disappears.

Note that the UI menu can use a different resolution to what the windows desktop is currently using; perhaps such a mismatch is part of the problem.

If I return windows UI scaling: (right click on desktop->personalize->display->Change the Size of all items) to 100% the problem goes away.

Steps To Reproduce

1. Set Windows desktop UI scaling to something large (e.g 200%).
2. Try to use mouse on menu screen (or inventory screen).

This seem to be a general bug with the Arma engine (based on Googling for it, not actually tried to reproduce on Arma games; e.g http://steamcommunity.com/app/107410/discussions/0/864961722064628960/ [^] http://feedback.arma3.com/view.php?id=246 [^] )
