Thread: Libreoffice and flickering colours in plasma5

  1. #1

    Question Libreoffice and flickering colours in plasma5

    I got a strange problem some time ago (several weeks already) and cannot fix it. In Libreoffice all colours are flickering when moving mouse over components (menu, icons..). It changes radically - like black to white and vice versa - making whole office toolset unusable. I've tried changing theme etc. but no solution yet. When I used different windowing system (Enlightment) then there were no issues with flickering colours. The flickering seems also be related to kinda double buffering i.e. when I go to Tools/options I can see something partially. And when selecting option from the left hand side the right hand side gets updated but the previous content is not erased. If I go to next option then something gets erased from right hand side but it's starts to be a mess. Checkbox icons are not visible etc.

    Compositor enabling/disabling doesn't seem to have any impact.

    Someone had issues with poor quality icons but this problem I don't have. Icons seem to be hire res.

    I've seen a very similar thing. If you're able to, try:

    Tools -> Options -> Libreoffice -> View

    disable "Use OpenGL for all rendering"


    If you're unable to make the change because of the flickering, then with LO closed temporarily rename "registrymodifications.xcu" (it's below ~/.config/libreoffice/[version]/user). That will result of course in default settings once again, so any changes you made will need to be repeated.

    I'm no longer able to login to Plasma 5 with my account. It simple loads indefinitely after login screen. Tried removing ~/.kde4, ~/.config, temp files under /var, ~/.local but none helped. According to x-session log even X fails to start for some reason. So something is wrong with my account but don't know what.

    I tested Libreoffice using different account and there is no flickering issue. So, trying to figure out now how to fix the account problem. Maybe I have to re-create it..

    What Video card? if NVIDIA did you make some sort of custom config using nvidia-settings???? If so you may have created a config file in your home. Think it is in ~/.nv But that is all guessing

    It's integrated Intel something. No special settings.

    I recreated the account and tried to log in but no. Did not work. .xsession-errors-:0 gives following output to my account with Plasma 5:

    Any idea why I cannot log in to Plasma 5 with my main account (even after re-creation of it) anymore? Works with other accounts. Something is corrupt/broken by what..

    If others work then problem is in your home. Have you removed all in ~/.cache. Also check ownership of files they should all belong to your user ID (UID) normally 1000 but that can depend on the history of the home.

    Like I wrote. I re-created the account so home was empty until folders and files were created by KDE. That's why this is so strange. Apparently there is something still somewhere that prevents Plasma and/or X to start properly with main account. Account is related to system administrator as well (system emails come to that account) but that's quite far fetched.

    There is no such thing as "main account" All accounts are more or less equal. The only magic user is root.

    So you now have a empty /home/somename account that should match your first user which is normally UID 1000? So that directory must be owned by UID 1000 and the name must match the name of the account with UID 1000. And caps matter.

    there are known issues with plasma 5 and intel graphics including libreoffice UI
    some of those issues are supposedly fixed but if you are having display issues on an intel graphic chip try using uxa acceleration
    create the file
    Code:
    /etc/X11/xorg.conf.d/20-intel.conf
    and paste this in it
    Code:
        Section "Device"
            Identifier  "Intel Graphics"
            Driver      "intel"
            Option      "AccelMethod"  "uxa"
        EndSection
    It's an old bug but I'm not sure who's working on it as it's not a kde bug and I've read it's fixed but I've also seen a lot of comments that it's still there
