Revisiting this since I’m encountering deadlock on macOS:
Seems like a JUCE bug… any thoughts?
Can you see if you get this problem when using SR’s JUCE branches (master branch is JUCE 4 based, juce5 branch is based on the JUCE 5 develop branch).
It contains changes to OpenGL on macOS (specifically using CVDisplayLink as Apple recommends) and it would be interesting to know if these changes solve your problem or not.
Hey, tried the branch juce5 but had the same issue (I guess). See original thread Opengl hosted vst plugin editor problem :(
