[cocoagl] Scummvm is crashing Retroarch in MacOS Arm M1

[Kulkoba]

After one of these last updates, it is not possible anymore to launch Scummvm core. Trying to do it crashes Retroarch.

Can you tell what's your last working version?
Also please provide retroarch.log with debug level set both for frontend and core.

[Kulkoba]

I am sorry not being able to tell what was the last working version. I don't know which version exactly as I don't remember when it was the last time that I have used the core. :-( Perhaps the previous version, or two versions ago, but I can tell with certainty.
I am not sure if this is the log you want but I am sending it here. I hope it helps.

Il looks like CocoaGL, doesn't natively support the GLAD loader for OpenGL functions, which is used in ScummVM.
So you should solve the issue disabling HW acceleration in the core options.

[Kulkoba]

Many thanks for the advice. That helped.
I don't recall changing this core preferences. Were the default preference and core preference files changed on the last version (having the setting enabled)? If that was the case, it may be affecting other Mac M1 users. ;)

[spleen1981]

Can you check if it works selecting GL video driver instead of GLcore and enabling back hw acceleration from the core settings? Need to close and re-open the core to apply this setting.

@Kulkoba any update?

[Kulkoba]

I am a bit confused. What do you want to test?
Your solution worked - I have changed the parameters below, disabling HW acceleration, and it's working now.

[spleen1981]

I am a bit confused. What do you want to test?

My understanding is that with retroarch glcore video driver and HW acceleration activated the core does not work.
I would like to test if with retroarch gl video driver and HW acceleration activated it works or not.

[Kulkoba]

Ok. I have shown you the parameters that I have now. Just say exactly what must be changed so I can test it.
I have changed scummvm_video_hw_acceleration from "enabled" to "disabled". Do you want it back to "enabled"?

[spleen1981]

I have changed scummvm_video_hw_acceleration from "enabled" to "disabled". Do you want it back to "enabled"?

Yes please enable it again.
Then from the main retroarch menu go to Settings > Video > Output > Video Driver and select "gl" instead of "glcore".

[Kulkoba]

Ok, so I have changed scummvm_video_hw_acceleration back to enabled and it crashed again.

On the video output I had "vulkan".

I have selected "gl" and it did not work.
After, I have selected "gl core" and it did not work as well.

After I have disabled the scummvm_video_hw_acceleration parameter, and it is works with vulkan, gl and gl core.
