BR: Coregraphics render with multiple paint calls is broken

[aamf]

Setting COREGRAPHICS_RENDER_WITH_MULTIPLE_PAINT_CALLS=1 seems to completely break the graphics rendering. It no longer updates and the UI becomes unresponsive. I am observing this using the DemoRunner on iOS 16.5 (Ventura 13.4, Xcode 14.3.1, latest JUCE develop tip, iPhone SE 2nd Gen.).

I’m not aware with which commit this started happening, though, sorry about that. I have just now compiled for iOS 16 after several months and seen this problem.

I was using it as a workaround for the issues described here:

Weird path rendering phenomena?

So, i have a weird phenomena here i cannot get rid of: here I am using a gradient to stroke a path. The path is just an open path. Sometimes (depending on the path’s shape) I get these weird horizontal pixels rendering. like the one in the top here. If I use solid color, this does not happen. It also happens to rounded rectangles with fillPath so it is not an issue with the stroke function. It does not happen with the software renderer This happened ever since I updated to 7.0.2 I have …

Those glitches also disappear if AsyncRendering is turned off.

Update: It seems that the glitches described in the thread have been fixed. After updating iOS to 16.5 they seem to be gone.
