[REG 5.10->5.11]: Painting issues appear on macOS when not using layer based views. For example, making a button disabled does not update it right away. Known related issues are linked to this one where they are all resolved by setting QT_MAC_WANTS_LAYER=1.
They are also working in Qt 5.12 already, but it is now clear what patch specifically solves it (unless its the change to having them use layer based views).
