[Bug 1490348] [NEW] Compiz randomly crashes X11 when resizing windows if defaul resize mode is set to "normal"


Public bug reported:

I am using compiz as standalone window manager and emerald as
decorator with kernel 4.1.6 on Geforce GTX 670 MX card (Asus GW75
laptop), drive 304.125, X11 1.17.2.

I have experienced quite many crashes, when resizing windows. I have
seen posts around the webb about Compiz being crashoholic, and tips to
switch applications switchers, turn off resize info plugin and so on. On
my system I was able to isolate Compiz crashes to Resize window plugin
and "normal" option default resize mode . Once resize option is changed
to anything else, rectangle, outline or stretch, the compiz stays rock
solid. I can use any switcher and resize info too (which I don't use coz
I think it is meaningless) and compiz have no troubles at all. I have
been using it now for a week without crash.

I am not sure what couses compiz to crash while resizing, can it be some
opengl setting maybe, I haven't had time to play around. I have
Compozite on, OpenGL on of curse, X11 sync objects is enabled, always
use buffer swapping, frame- and vertexbuffer object and texture
compression are all enabled.

I am able to reproduce this almost every time I enable resize mode to
normal painting, albeit it can sometimes work for hours without crashing
and sometimes it can crash almost immidiately. so I guess it can have
something wth memory managment to do? Some pointer that go mad after
some cleanup or something?
