I've tagged this bug as affecting me as well, but need confirmation of whether we're indeed in the same situation or not.
My Xorg process (/usr/bin/X) consumes more and more memory as time passes when any "OpenGL x.x" option is selected in KDE Desktop effects' "Composite display mode" parameter (on the "Advanced options" tab). Selecting "XRender" option instead "OpenGL x.x" fixes this - what looks like being a - memory leak issue but I lose the benefit of OpenGL desktop effects :( I didn't figure out if memory consumption increases faster or not when playing Minecraft, but the fact is that after several hours of gaming, I could end up with Xorg consuming ~ 2 GB :( Unless my KDE is configured to use the "XRender" composite display mode as explained above. I'd suspect the AMD fglrx proprietary driver to cause this memory leak, while not being totally sure of it... $ fglrxinfo display: :0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc.
