Windows 7 64-bit, VS2015 SP1, HEAD (382205)

Set display to a non-native resolution. (I'm running Boot Camp on a 13" MacBook Pro, which has a native resolution of 2560x1600, but I run it at 1440x900.)

ninja -C out/Default mash:all
out/Default/mojo_runner mojo:mash_session
Crash, though I'm not clear which process is dying here.

The problem doesn't happen at 2560x1600, or at 1280x800 (exactly half).

I see a note from erg@ about DPI in DefaultPlatformDisplay::SetCursorById() that might be relevant.
