    Description

      [macOS 10.14]: When using WA_NoSystemBackground and doing minimal updates to update a specific area then it is not painting those updates. Unless something triggers it to update the window as a whole, such as switching active windows or resizing.

      This seems to be specific to macOS 10.14 as it is working fine in macOS 10.15.
