[Bug] Issue with setBufferedToImage and Direct2D Rendering in JUCE 8

[pstitt01]

Does it happen in all DAWs?

DocumentWindow has problems when it is transparent since JUCE8 that are apparently DAW-dependent. They’re quite different problem but both linked to transparency.

BR: DocumentWindow broken in VST3 when transparent since JUCE 8

This is a bit weird. I’ve started investigating, but haven’t made much progress yet. Interestingly, the issue doesn’t seem to affect all VST3 hosts. REAPER is affected, but the JUCE AudioPluginHost isn’t. So far I’m not sure what causes the difference in behaviour.
