Version: unspecified (using Devel) OS: Linux When I change a configuration option in systemsettings that affects kwin (such as adding/removing desktop effect, configuring "window behavior"), kwin becomes semi-dead and needs to be --replace'd. Semi-dead means that windows do not get shown/hidden on alt-tab or desktop change, which makes general work unusable. The --replace works only half of the times, sometimes I have close the X session altogether. Reproducible: Didn't try Relevant software versions: Qt: 4.6.3 KDE Development Platform: 4.4.92 (KDE 4.4.92 (KDE 4.5 RC2)) KWin: 4.4.92 (KDE 4.4.92 (KDE 4.5 RC2)) X.Org X Server 1.8.99.904 (1.9.0 RC 4) Module radeon: compiled for 1.8.99.904, module version = 6.13.1 Linux 2.6.34.1 SMP x86_64 (with KMS)
please have a look at bug #241402 - do you think it's the same? a) is it related to compositing? b) can you - switch the active window using the mouse? - drag around windows? c) do windows still update their content?
a) yes -> does not happen with suspended b) no, no c) no The trick with alt shift f12 works to revive kwin. If it's the same as bug #241402? You tell me.
seems to be the same bug *** This bug has been marked as a duplicate of bug 241402 ***
