    Default Strange/annoying behavior with icons in Opensuse 12.1/KDE4.7.2

    Hi,

    I noticed a very frustrating behavior regarding icons in the task manager in my OpenSuse 12.1.
    I have a pretty old PC (Pentium D/3 GHz and 1GB of RAM) and from time to time my icons from the task manager just dissapear (icons I place there with the option "Add to panel" from right-click at the icon in App Launcher). I', not saying the icon just vanishes, they are still there, but just won't be visible -- I mean the place where they were is still occupied, when I hover the mouse over them, I still got that tooltip from them, I can still click on them and launch the program, or right-click on them and get the context-menu -- they are working, but just not appear in the taskmanager !!!!
    And the only work-around is to just logoff and login again !!!!
    You can imagine how frustrating this is !!
    Is there any way I can revive those icons when this is happening ?
    If I just delete such an icon from taskmanager, and then re-place it there (from App Launcher via that option "add to panel") it still has the problem (not visible, but working good otherwise) !!!!

    I have the same version (Opensuse 12.1) installed on another PC, with more RAM (2GB) and a little better processor, and this thing is not happening, so I guess is something related to scarce memory resources, but ... WHAT ?

    Any suggestions as what can I do to avoid this ? (or at least, make them appear again, without logoff/re-login, or rebooting my PC)

    Thanx

    Okay ... things are, unfortunately, even worse (much worse).

    The same thing happen with applets that are started and stays there, in the down-right corner of the screen, like the clippboard icon, or the volume (kmixer) icon !!! (actually, right at this moment, my kmixer icon is not visible -- though I can right-click on it and open the kmixer window from the contextual menu ....
    It's soooooooo frustrating !


    Even worse .... similar thing happen within Dolphin, with those arrow buttons (back, up, forward) !!! Only workaround is to close Dolphin and re-open it after that.
    Even in Firefox, things happen the same (as in Dolphin, with the back/forward icons at Firefox's toolbar).

    That's something I cannot understand ... I'd say it's KDE's fault, but since it only happen on this particular PC (which I admit, lacks some RAM -- nonetheless, I don't think KDE should behave this way even in such low-memory conditions -- and after all there is still 1024 MB of RAM, not less) does anybody have similar behavior, or even better, have some clue about what can be done about it ?

    you don't say if it has been like this from first install or not, but
    i guess it is a video driver problem...

    if it has always been like that then i guess _maybe_ there is a better
    driver that can be installed by carefully working your way though:

    if it suddenly and noticeably started happening after an update,
    application install, or etc then it might be more involved...

    and, another thing you try (to avoid log off/log in) would be to turn
    off desktop effects (and don't use compiz)

    not sure, but this might be related:

    some users experience these bugs, others (incl. me) never saw them.

    Oh, yes, unfortunately, this happened here from the beginning ... it isn't (or I don't find any relation) related to a certain update.
    Well ... it could be due to the display driver, yes -- I only have an embedded Intel video card, so .... I wouldn't be too surprised to be due to this (though ... it didn't had all these strange behaviors with older Opensuse versions -- this PC managed to work with all elder versions way back to 11.1 I think ...). The actual video driver in use is the default driver installed (video controller is an Intel 82495 as I see in /var/log/messages )

    Ahh... yess ... the first mentioned bug hit me too.
    I, too, experience that behavior (sometimes (impossible to say when, or after how time, or in what other conditions) I close some window, but it's title still remains present on the taskbar, as if it would still be active (of course, clicking on it doesn't do anything); in order to get rid of this remnant app from the taskbar, I have to start another program (usually start that program again -- say Thunderbird).
