    Hi all,

    i recently upgraded the Qt5 version for our i.mx6 target from v5.6.3 to v5.9.8.
    Now, if i start the application, loading a font e.g. "NotoSansCJKjp-Black.otf" takes about 5s (Qt 5.6.3 ~ 62 ms).

    Has anybody an idea?

    Regards,
    Christian

      Hi,

      Sounds like a regression.

      Did you already check the bug report system ?
