After upgrading from JUCE v4 to JUCE v5, our UI is completely broken. I’ve traced the issue to LookAndFeel_v4. The code is fine if I check out commit 3b422bef51ce741838ed54363efaaa502c7b1ca1, but breaks if I check out commit ef2c63e4e324b75cdb7e13dc5ff5d519d8b146a8 in the JUCE repo.
ToggleButtons and Labels are simply not rendered. Are there any obvious changes that were made from LookAndFeel_v3 to LookAndFeel_v4 that could cause this?
