Bug: juce 6.0.6 breaks on macos (but not ios)

when i updated to 6.0.6 my app no longer worked. all windows were black and the debug console is full of this line:

2021-01-13 14:55:34.801749-0800 Instrument Designer[11531:65731] [sc.modo.instrumentdesigner.osx] CGImageCreateWithImageProvider: invalid image provider: NULL.

git bisect helped me trace it to this commit - when i revert that commit locally everything works as expected.

i checked the example standalone plugin and it seems to work fine - any ideas what could be happening here?

A minimal example that triggers the problem would be very helpful. It’s difficult to say what might be the cause without more information.

This happened to our Waveform app and plugins in Release builds (not debug though).
I tired building the JUCE demo but that seemed to be ok though so still digging for a proper report.
This happened with both the 11.1 & 10.13 SDKs targeting 10.9.


Thanks for reporting, there was indeed a bug in that commit with JUCE_COREGRAPHICS_RENDER_WITH_MULTIPLE_PAINT_CALLS enabled. We’ll be doing a bugfix release very shortly with this fix in:


thanks @ed95 , this works for me.
