Hello, just upgraded to 10.11 El Capitan and mame full-screen mode is off-center. The top of the screen is pushed several pixels down which is cutting off the bottom of the viewable area. If I toggle full-screen to windowed mode and back, it is corrected. Anybody else seeing this? Thanks.

mame 0.166 on Mac OSX 10.11 (build 15A284)
iMac Retina 5K 27" Late 2014 with Radeon R9 M295X

I can't reproduce that behavior. I set window to 0 in mame.ini and everything is displayed just fine. Is there another option that you did activate?

Well it's not happening on my MacBook Pro, only on my iMac. I tried creating a new generic mame.ini, erased default.cfg settings, and it happens every time.

Here are a couple of screenshots showing the issue. The entire image is pushed down. As you can see the bottom gets cut off. Anybody else have an iMac running 10.11 yet?

I have a 27" iMac (not the retina display) running 10.11, and I'm not seeing this issue.

I'm trying to come up with a plan to fix OS X, since SDL 2.0.4 is on indefinite hold while they screw around with DOTA 2 (This is the official excuse on the dev list).

Vas, if you're reading this, please advise, you've forgotten more about OS X than I know.

Options
1) Convert SDL platforms to GLFW.

Minuses: no audio support (not a problem on OS X, and I have a workable PortAudio backend banging around my tree too), and they don't ship a nice pre-packaged framework so we'd probably need to import it into 3rdparty/. No OS/2 support.

Pluses: Handles multi-monitor and Retina smoothly on all OSes, including OS X.

2) Custom CoreVideo backend, maybe based on MAME OS X's old code?

Minuses: might be difficult to integrate with the -video opengl and bgfx options. Multi-head support unknown.

Pluses: Gives the OS X more a more Mac-like flavor, allows possibility of using CoreVideo filters like MAME OS X.

3) Full-custom Cocoa backend.

Pluses: we own it, we can't be held hostage by middleware developers with other priorities, we can possibly add some Mac-like features like dragging-and-dropping a ROM zip onto MAME. I have some relevant experience with this now having written platform glue code at work to get us an OpenGL context on the Mac in a window or fullscreen.

Minuses: Large-ish amount of work, especially to support multiple heads and Retina.

4) Other: suggestions welcome.

I'm kinda time-starved at the moment, sorry for not being more active. My MAME backlog is piling up. If I was going to do CoreVideo output, I'd probably start from scratch and mostly ignore MAME OS X code. It's one of those things I've toyed with the idea of but not got around to. GLFW has the advantage of getting us uniform input handling across platforms. If we were to go with one of the other routes we'd have to do HID input directly or use something like DDHIDLib. I'm kinda tempted to write custom input code anyway, just to deal with stuff like pen tablet input properly.

Just wanted to report this bug was finally fixed by updating to SDL version 2.0.4

Awesome. I was hoping that would be the case!
