Version: (using Devel) Compiler: gcc 4.3.3 CFLAGS="-O2 -march=pentium4 -pipe -fomit-frame-pointer" OS: Linux Installed from: Compiled sources After some hours using kde 4.3-svn frames, buttons and other widgets start dissapearing. Once it starts dissapearing widgets all the plasmoids, buttons etc dissapear in some minutes. It's possible to use them (you can clik on them) but they're fully transparent or something similar
More info: When the widgets start to dissapear I get these lines all the time from plasma-desktop STDOUT: QPainter::begin: Paint device returned engine == 0, type: 3 QPainter::setCompositionMode: Painter not active QPainter::end: Painter not active, aborted
Thanks for reporting. What is your Qt version ? What is your KDE version (svn revision/branch)?

I have similar problems. Here my KDE/Qt versions: KDE 4.2.70 svn954171 Packages from openSuse UNSTABLE-repo QT 4.5.1 Packages from openSuse Qt-repo Additionally I use the latest radeon driver from XOrg-repo. Plasma-Theme in use is Air. Plasmoids used besides the default: Microblogging (2 times) Networkmanager

that was due to various pixmap leaks in the systemtray widget, Qt and potentially elsewhere. depending on the graphics card/driver set up it would do various things in response once resource usage topped out. in any case, we've tracked the problems down in kde 4.3 and qt 4.5, so this should "magically" go away with the upgrade to the upcoming kde and qt releases.
