My .xsession-errors file is now almost 1 GB in size due to QPainter's frequently spitting out messages like the following: QPainter::hasClipping: Painter not active QPainter::setClipRegion: Painter not active QPainter::setClipRegion: Painter not active QPainter::hasClipping: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::drawRects: Painter not active Probably this is not a problem with QPainter itself but with something else that is misusing it. That something else might be Konqueror. If I follow the tail of .xsession-errors, I can see these log output lines filling it up by the screenful while I mouse over the text input components on this bug report page into which I'm currently typing this report. Bunches of QPainter messages are spit out every time the cursor blinks and every time I press a key on the keyboard. Here's how I have qt-gui and kdelibs installed: $ emerge -ptv qt-gui kdelibs These are the packages that would be merged, in reverse order: Calculating dependencies... done!

It isn't really a bug, some code just haven't been fully ported yet. It's marely a warning.

Is there a way I could temporarily disable redirecting the stderr of my KDE session to .xsession-errors for the time being? I don't want a multi-gigabyte log file sitting around.

The .xsession-errors gets setup from /etc/X11/Sessions/Xsession
That bug just made two of my X-sessions crash pretty hard. Symlinking ~/.xsession-errors to /dev/null didn't work, as the symlink got replaced by a regular file upon relogin (which filled up at a rapid pace, too).
This is not alone a QPainter problem. For example, kate(part) emits several lines of output whenever you select some text with the mouse. Also, starting e.g. okular from a terminal with "okular file.pdf &" makes that terminal pretty useless... Since this is a real pain for users with disk quota, I'll make it "major". However, it's something that upstream has to fix...
Isn't this fixed in 4.4.2? http://websvn.kde.org/?view=revision&revision=1105396

Still not great, but good enough in 4.4.2 to close this bug I think.
