Description Sam Duke 2013-05-16 02:25:26 UTC

I noticed a few days ago my Xorg process was eating up 800MB of memory. PMAP showed lots of (deleted) entries: http://pastebin.com/nHbU3gjL
I rebooted, ran xrestop and waited a couple of days and the culprit seems to be plasma-desktop.

I've run plasma-desktop in valgrind, which crashed after about 10 minutes, but I did get an output showing some memory leaks: http://pastebin.com/s71DanwU

Special note about my setup: I have an laptop with optimus and I'm using Bumblebee. Although I wasn't using optirun during any of my issues.

Reproducible: Always

The laptop is an ASUS N55SL if you need any hardware info.

    Fix X pixmap leak in shadow handling code
    
    Some X pixmaps were never free-ed. The code got a little bit cleaned up
    by ensuring that the X Pixmap for the QPixmap is always created. This
    makes sense as we can be pretty sure that we are on the raster graphics
    system.
