[Valéry AMIOT <1419111@xxxxxxxxxxxxxxxxxx>]

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.
OpenGL renderer string: AMD Radeon (TM) R7 300 Series  
OpenGL version string: 4.4.13374 Compatibility Profile Context 15.20.1013

$ apt list fglrx
Listing... Done
fglrx/trusty-updates,now 2:15.200-0ubuntu0.3 amd64 [installed]

Any feedback appreciated :)
