Wayland clients crash with window titles longer than 4k characters with unicode characters

    XMLWordPrintable

Details

    • Linux/Wayland
    • 1ed0782e93dafb0a3d5ef3a02c9c3999825817ee (qt/qtwayland/5.13) 45859d7521074a4921b8459eb0a6e2cc71b9dd5a (qt/qtwayland/5.12)

    Description

      Title says it all. We fixed this previously, but we truncate based on characters in a QString, and in the end the title is utf-8 encoded, so 1 char != 1 byte and we still overflow.
