Thread: Fonts become blocks for firefox, thunderbird, libreoffice

    Default Fonts become blocks for firefox, thunderbird, libreoffice

    Recently (in the last week or so) firefox, thunderbird and libreoffice fonts all turn to blocks (black rectangles) after a minute or two.
    I have completely reinstalled the OS with only the default repositories (not even packman) in case I had some oddball problem there - but the problem remains.


    Here is an example of what it looks like...
    http://www.greenbikers.net/dokuwiki/...c:compute:font


    when I first run thunderbird or firefox they look fine, then for no reason I can discover, as I move the mouse over the fonts they turn to blocks.


    Applications affected...
    firefox, thunderbird, libreoffice, ksnapshot, gnucash


    Applications not affected...
    xemacs, konsole, kde desktop, konqueror, dolphin


    System details:
    opensuse 13.1
    kde desktop

    nvidia-gfxG02-kmp-desktop-304.121_k3.11.6_4-31.1.i586


    Other machines I have are fine (32 bit laptop, 64bit laptop)


    Help desperately sought! Thanks in advance

    I had a similar problem on a computer with Intell G33 graphics. It happened only on some gtk applications, but never on native KDE applications.

    I never had a problem on my system with nVidia graphics.

    I suggest you experiment, in firefox, with the settings for graphics acceleration. And also try experiment with the options for xrender. For the latter, you will need to browse to about:config and then search for xrender.
    openSUSE Leap 15.1; KDE Plasma 5;

    Well, the trouble is this affects more than just firefox - thunderbird, libreoffice, gnucash (at least).
    So I don't believe it will be helpful tweaking firefox specific configs.

    It seemed to go away for a few days, then bingo, today it has happened again for no reason I can fathom.
    Surely this must be a well know problem - anyone else out there know what's going on?

    Thanks...

    There is a definate correlation with this problem and using nvidia drivers (G02), version 304.121.

    Anyone else had and fixed this problem?

    I general when you have problems with browsers crashing set them NOT to use hardware graphics.

    Except it's not just the browser. It is thunderbird, libreoffice, gnucash, and even the window titles on the kde desktop. Any other thoughts? Thanks...

    OK - so I think this was the issue: the graphics card (its memory I presume). The problem got progressively worse and started happening with the nouvea driver also and start causing panics. Swapped the card and all is fine - including with nvidia driver.
