setNeedsDisplayInRect broken on Sonoma?

[zsliu98]

I can confirm that this issue does exist (on macOS 14.1) and JUCE_COREGRAPHICS_RENDER_WITH_MULTIPLE_PAINT_CALLS=1 works for me. However, it uses dGPU now (IIRC, before macOS 14 it used iGPU).

I reported this issue about one month ago. Thanks for your explanation. Now I understand why the level meter is slow: it tries to repaint the whole window even if only the level meter calls repaint.

Sonoma Rendering Issue

I can confirm that one of my plugin also has a rendering issue on macOS Sonoma (Intel chip). The level meter is not able to render smoothly (should be 60Hz, trigger by a Timer) and eats much more GPU than before (source code is available here, a little mess ). this plugin renders smoothly on Win10 virtual machine on the same MacBook Pro another plugin which renders an oscilloscope (by OpenGL) still works properly
