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?
