Product: SDL Reporter: Eric Wasylishen <ewasylishen>
Component: *don't know*Assignee: Ryan C. Gordon <icculus>
Status: RESOLVED FIXED QA Contact: Sam Lantinga <slouken>
Severity: normal

Version: HG 2.1

Description Eric Wasylishen 2014-05-18 03:53:29 UTC 
Steps to reproduce:

- Run testwm2 app in the SDLTest Xcode project
- Press Control+R to enable relative mouse mode. The mouse cursor should disappear.
- Press Control+Enter to enter fullscreen.
- Expected: a black screen with no cursor visible. Observed: a black screen, but the mouse cursor is visible in the middle of the screen. It doesn't move when I move the mouse.

Reproduced with latest sdl2 hg (changeset 29aac8b813d9) on OS X 10.9.2. Can't reproduce the problem on OS X 10.6.8 or 10.7.5.

proposed fix

I'm speculating that this really an Apple bug.. but anyway, the attached workaround seems to fix it for me, and I think it's fairly safe.

A more obvious idea, sticking a call SDL_SetCursor(NULL) at the end of Cocoa_SetWindowFullscreen, didn't work.
