|Tester||estefan3112||View Status||Public||Platform||MAME (Self-compiled)|
|Assigned To||Resolution||Not fixable||OS||MacOS X|
|Version||0.182||Fixed in Version||Build||64-bit|
|Summary||06476: all: bgfx - metal crashes since 0.177 in every version|
Since version 0.177 of MAME, bgfx-metal crashes/does not work. I could reproduce this both in El Capitan (0.177 - 0.179, and these systems also crash in MacOS Sierra), since 0.180 in MacOS Sierra. In younger versions, MAME does not crash, but produces no picture.
Latest error message under 0.182 after exiting the system:
CoreAnimation: warning, deleted thread with uncommitted CATransaction; set CA_DEBUG_TRANSACTIONS=1 in environment to log backtraces.
Same happens with the officially compiled version of SDLMAME. MAME 0.176 still works in my current environment.
PS: I could not report earlier because I have real troubles with logging in in MAME Testers if I am using the MacOSX Password Manager -> I get immediately kicked out again.
|Steps To Reproduce||
./mame64 -video bgfx -str 60 -noafs -bgfx_screen_chains crt-geom-deluxe -bgfx_backend metal -artcrop -noreadconfig -nosleep -nothrottle gyruss

Crash has been confirme by one visitor of my blog.
As indicated by Tafoid below, the command works under Windows, however, since Metal is an Apple API requiring El Capitan or newer, my assumption is that 'metal' is ignored in the MAME Windows version.

At least for Windows, your command lines seems to work (had to take out -noreadconfig which had my path settings). I'm able to see and hear Gyruss without issue.
Hopefully someone else on MAC OSX can test.

|I have added this in my report: Metal is an Apple API requiring El Capitan or higher, so my assumption is that the MAME Windows version just ignores 'bgfx_backend metal'.|

From what I was told from our current project leader, the metal backend support is preliminary through BGFX and was never fully supported. The BGFX project, https://github.com/bkaradzic/bgfx , is entirely responsible for it working or not and the fact that it works for one platform and not another is a matter of luck. You may be able to address your issues directly with them as it falls beyond the scope of our bug coverage. It is suggested to use OpenGL 3.
Again, this is nothing we can address or fix on our end.
Closing this report.
