Critical Issue on macOS Apple Silicon - UI Lag

foxfox

We are experiencing severe usability issues with Live2D Cubism Editor 5.2.02 on macOS Apple Silicon devices (tested on M1/M2, macOS 15). The problems make the software nearly unusable for professional workflows.

1. Core Issues
1.1 Unresponsive UI and Input Lag
Button hover effects delay by 2-5 seconds.

Canvas dragging/zooming stutters.

Lag persists even with all other applications closed.


1.2 NullPointerException in AWT Thread
Random java.lang.NullPointerException during operation, often tied to UI events

3. Troubleshooting Attempted
Solution Result
Forcing OpenGL/Metal via JVM args No improvement; Metal backend shows 4.1 Metal - 89.3 but unstable
Disabling UI scaling (-Dsun.java2d.uiScale=1.0) UI elements render correctly but lag remains
4. Critical Questions for the Team
Is there an official timeline for Apple Silicon (ARM64) native support?
Will you provide updated JOGL/OpenGL native libraries compatible with macOS Metal?

Just wanna chiming in, I've been using Live2D on my MBP M1 with no issue, and also had chance to test it on an M2 as well. So I'm not sure what's your situation is. Have you downloaded correct build from their website? They have both Intel and Apple Silicon builds as separate download.
