    Default Font rendering issue

    Hello,

    I have an Qt application for embedded linux on MIPS.

    We are facing problem with font rendering on text which is set to QLabel. Its working fine generally but sometimes the font rendering displayed like distorted and holds this behaviour untill we restarts the application. This font rendering distortion is noticed on display screen and the printouts we have generated using our application.

    I am using style sheets to specify the font size and family.

    I have experienced similar issues and I have found that the text render sometimes does not cache the fonts that you have loaded and will reload them with default fonts, which could explain the distortion that you are seeing. I specializes in low level graphics, 2D and 3D, text & user interface development for embedded platforms. If you need any more help let me know.

    Question Re: Font rendering issue

    Hi,

    I am using 4.5.3 version and the TrueType fonts are NOT displayed as smoothly as they are done in my firefox browser.
    I am using PreferAntialias and PreferOutline, but it does not help. Is this a rendering issue or something else?

    Thanks,
    Dinesh

    Hi All,

    Any update on this issue?

    I am using qt-4.8.7 on ubuntu 14.04.
    Fonts are coming as distorted for me as well. It is working fine for further versions of QT but i have to fix it with QT4.8.7 only.
    Please help if someone was able to solve this issue.


    Thanks in advance.
