Metal: Problems with arrow keys and games don't launch
When using Metal, either the up or down arrow key on the keyboard doesn't work, and the menu UI is slow. Additionally, games no longer launch.
macOS 26.1 (Apple Silicon) RetroArch 1.22.1
Same here. Just noticed yesterday. macOS (Apple Silicon) version of RetroArch. The main menu is very laggy when using keyboard or gamepad controls, whether or not a game has been started. (The menu is more or less fine when driving with the mouse, though...) RetroArch 1.22.0 and 1.22.1 both have this problem. (1.21 did not.)
It seems that I can launch a game if I start RetroArch with the game in command line arguments (which is what I usually do), but trying to start it from the menu doesn't always work.
Similar problem on Intel iMac (late 2013, i5) running macOS Catalina 10.15.7. Menus work fine before launching any game; when I do, the game rarely starts at all and when I get back to the menus they stutter and read the inputs from the keyboard very slowly.
Do any of these problems reproduce in vulkan? I have no plans to fix any problems in the metal video driver and the more problems that get reported against it increases my impetus to delete it.
Switching to Vulkan doesn't solve the problem for me, same behaviour. But then again, my machine and my OS are very old. I don't think my situation is 'standard'. =)

Did you try to restart RetroArch after switching driver? I had to restart RetroArch before it had any effect.

Yep, but no dice. I'll make some more tests as soon as I have a little time. =)
What I find really weird is that it's supper laggy but if I keep my mouse moving it works fine™. Here's a quick clip of what I'm saying: https://github.com/user-attachments/assets/71bc32da-9bdd-49a6-b9a0-fb8e15f986ca Captured on Retroarch 1.22.2 with the DeSmuME Core running Mario & Luigi - Partners in Time (Europe) Here's the log file: retroarch.log
@Shrapnel21 for you specifically, try a nightly build from later today. There was a bug that affected versions of macOS older than 14.x.

It actually seems I have no more lag on the interface, but I have to set it to Metal (it defaults to Vulkan) because I only get a black screen when launching a game with Vulkan. But, again, that might depend on the old version of macOS I'm using. =D
Wait, the menu works fine in vulkan but the games don't? Which cores?
I only tried Neko Project II so far, I'll make some more tests.

Confirmed: menus work with Vulkan, but when I open games I can hear sounds, but only get a black screen. When using Metal, both menus and games look fine. And no more lag in the menus either way.
