[virtualBox] While rendering QT apps the screen doesnt show text completely on mac.



  • Virtual box with Mac (High Sierra) host.
    Guest OS : other linux 32 bit (webOS)

    Issue:
    while rendering QT apps the screen doesn't show text completely.
    it happens only in Mac host.

    Example:
    One of my app shows similar to a virtual keyboard. which shows alphabets and numbers as a keyboard.

    Few alphabets are not displaying at their respective position, the box shows blank.
    The not showing alphabets are not consistent, every time its different when launched.
    title at times comes and goes like a flash.

    Images are working fine though.

    I wonder if its a QT issue or not? please help.

    Did this directly on Mac ? I suspect the issue with your guest OS not rendering the contents properly.

    I am using virtualbox in between.
    virtualbox on mac host and then guest os as webos Linux 32 bit.
    but the same guest OS is not creating the problem in windows and Linux.
    so I suspect if there is something related to mac.

    Hi,

    Are you using the same version of VirtualBox on all OS ?
    Did you install the guest tools each time ?

    sorry for replying late.
    the setup is exactly same if we take version number or extension pack and everything.
    the procedure is also same to install the apps or to launch the toast message.

    other example could be a toast message which comes only once and when we change the text it goes off. randomly only new char are shown the old ones goes off.
