-- Information about the crash:
- What I was doing when the application crashed:
I'm not exactly sure how KWin crashed, but I was watching a flash video
in Chromium. It ended and I alt-tabbed and things locked up. Suddenly a
Chromium tab was in it's own window like I had dragged it off the tab
bar, but I hadn't. Not sure if this really helps or not.
This is on an R400 Thinkpad laptop with intel i945 graphics. KWin works
fairly good with effects but these intel drivers are really buggy it
seems.

Notice that "resolved upstream" does not mean that there's a fixed driver available atm. but just that the bug won't/cant be fixed in kwin.
in this particular case there might be a workaround available as discussed in #241402

I changed glXSwapBuffers( display(), glxbuffer ) with

The number of occurrances does not say much. That code is executed in each
fullscreen rendered frame (e.g. present windows, login, logout, desktop grid,
cover switch...)

We will definatly not change the code to workaround it - sorry. If it is
broken in the drivers, it has to be fixed in the drivers.

is it really the source of /this/ particular backtrace that occurs in a complete different location than glXSwapBuffers?
In case this might be a /very/ valuable information for the driver
developers and should definitely be fixed there, since a constant
glClear/glXSwapBuffer cycle is probably one of the most occurring GL
code statements.

I don't have the same backtrace. I have a backtrace like Magnus

all backtraces I have was very different. All crashes occurs when there
was a full-screen application(like flash or wine game) and another
window is appears.
For some reason internal structs of mesa become damaged(render buffer's
pointer for a region become 0) after glXSwapBuffers. Some mesa
functions(like prepare_wm_surfaces) were not expecting it and crash
kwin.
Chris Wilson has added the non-null region pointer check for
intelClearWithBlit function, so I not saw first backtrace. I made all
functions to work with structs damaged this way, kwin stopped
segfaulting, but, instead, it became very unstable(black screen, mouse
pointer freezing, flickering, etc).
I am trying to understand why structs damaging.

No, that's another -likely unrelated- bug :-(

yes - reasonable, but not related to this issue at all.

nullpointers are not exactly "damaged" like "dangeling pointers" but can be valid states, they might however require different treatment (reallocation or whatever) than a simple
"if (!pointer) return;"

I think that the two backtraces are consequences of one bug. Because
1) Developers marked my bug https://bugs.freedesktop.org/show_bug.cgi?id=33496 as a duplicate for 30509 and 30509 has the same backtrace as this.
2) Here is a patch for the first backtrace:
+ if (irb == NULL || irb->region == NULL)
+ goto clear_bit;
+
Here is code, that causes a segfault in my backtrace:
irb = intel_get_renderbuffer(fb, buf);
struct gl_renderbuffer *rb = ctx->DrawBuffer->_ColorDrawBuffers[i];
struct intel_renderbuffer *irb = intel_renderbuffer(rb);
struct intel_region *region = irb ? irb->region : NULL;
brw_add_validated_bo(brw, region->buffer); // irb->region == 0 -> crash
There is one simple way to figure this out - apply proposed patch and
check if each bug if gone. I'll be happy if someone check it.
---
I am logging most activity of kwin, mesa and libdrm and found that a mesa's function intel_region_alloc_for_handle unexpectedly returns NULL. I'll going to talk about it with upstream.

I have been testing and these are my findings:
Mesa 7.9 classic - no kwin crashes
Mesa 7.11-devel classic - no kwin crashes
Mesa 7.10.1 gallium (natty default) - kwin crashes whenever you change window decoration, color scheme, turn on/off effect, turn on/off vsync etc.
So problem seems to be in Mesa 7.10.1 gallium.
All these tests are performed on KDE 4.6.1 with radeon driver.

wrt comment #28, i experienced exactly the same crash as initially
submitted when returning from flash full screen in Chrome albeit I have
Mesa 7.9 installed (i915 Intel driver 2.14.901 running with KDE 4.6.1).
Did not try with Mesa 7.11 version.

Check out https://bugs.freedesktop.org/show_bug.cgi?id=32534 for my analysis
of how the region-less intel_renderbuffers get created. The net is that
something is closing the last handle to a GEM object and then trying to
retrieve it with a "name" that is no longer valid (because the object is
garbage collected when the last handle that references it is closed).
glXSwapBuffers
Mesa is swallowing the error and creating unusable renderbuffers, rather than
properly bubbling it up the stack. (The "fallback" that was added with commit
13bab58f04c1ec6d0d52760eab490a0997d9abe2 simply defers the crash in this case.)
I suspect that the race is somehow related to glXSwapBuffers. If I attach to
KWin with gdb and set a breakpoint in glXSwapBuffers, I am unable to
reproduce my crash (unlocking GLMatrix). I am not 100% sure of this,
however; the race condition combined with the fact that the crash occurs
some time after the actual problem is making this incredibly difficult to
debug.
Any suggestions would be welcome.

I am not so sure about it being the cure for this problem. Since the release of Natty, we got quite some duplicates and Kubuntu disables unredirection of fullscreen windows by default.

As an answer to Martin's last blog (On Stability) about the major

my T400: go to Desktop Effects in System Settings > Advanced tab >
uncheck 'suspend desktop effects for full-screen' (this may give a hint
for developpers as the crash appears in fullscreen mode when desktop
effects are resumed, e.g. upon a KDE notification or after fullscreen
mode exit ... but i'm not a geek). I'm running Kubuntu Natty 11.04 with
KDE 4.6.2 and xserver-xorg-video-intel 2.14 (the Natty official one).
With Maverick 10.10, I used to subscribe to ppa:callegar/xorg repository
with page flipping disabled in xserver-xorg-core, but it has not been
built yet for Natty (expected in a week or two).
Now, coming back to your concern Martin, my KDE 4.6.2 is very very
stable (apart from this serious issue). I did not experience any pb so
far. Be proud of your work!

can you do a semi-geek think, run konsole and:
mv ~/.kde/share/config/kwinrc ~/.kde/share/config/kwinrc.bak
(store your settings)
kcmshell kwincompositing
-> check the 'suspend desktop effects for full-screen' setting and report its state

So it seems confirmed that Ubuntu does NOT patch the FS unredirection

If this issue is not fixed till 4.7, I'm going to change the default, given that we now have the better

Perhaps Dr. Konqui could be improved here so if people try to add info
to a report that is marked as closed/resolved/etc... it will warn them,
or something.
Also, with the number of duplicate reports and additional info reports
from Dr. Konqui on this report, it seems like it should be pretty
important for intel/mesa to fix, but doesn't seem to get much attention.
Perhaps everyone that has ran in to this bug should go spam the
freedesktop.org bug report so the driver bug gets fixed and Martin's
head doesn't explode.
Thanks Martin, for all the work that you do and putting up with this bug

Disable Unredirect Fullscreen Windows by default
Well we don't have another choice if half of the drivers crash kwin
whenever you watch a fullscreen flash video or use a screen saver.
Unredirect Fullscreen Window was quite useful in case you used
to play heavy OpenGL games, but pretty useless for anything else.
For the game and hd video usecase we nowadays have the better way
of really suspending compositing (either by the client indicating or
with a window specific rule). The plus of suspending compositing is
that the driver doesn't crash.
And yes we are "supposed" to no longer workaround driver bugs.
Good joke, I like to redirect my inbox to everyone who things we
are not allowed to workaround driver bugs.

I have a question about your "workaround." It does work, in the sense
that going to full-screen flash videos and back doesn't crash kwin. But
it doesn't play the full flash video either. Instead I got just the
YouTube video controls over a black screen. I'm using a wrapped version
of 32-bit 10.3 flash on a 64-bit firefox, if that matters.
Just a confirmation or denial will be fine. I don't want this bug
report to become a flash debugging thread.

@Anthony: Didn't see your pb so far on my laptop, at least since 11.04
upgrade: flash fullscreen mode now works flawlessly. I did notice a few
months ago (Maverick 10.10/KDE 4.6.2 with previous xserver-xorg-core,
xserver-xorg-video-intel and flash plugin versions) that some flash
videos did not appear fullscreen from time to time, and a black screen
was displayed instead. Yet, the occurence of this issue was a bit
erratic (not with every site, meaning it used to depend on the specific
embedded flash video player), and I was able to fix it by reloading the
HTTP page and triggering again the fullscreen mode. Seems your issue is
more related to the flash plugin. FYI, I'm using flashplugin-installer
10.3.181.14ubuntu0.11.04.1, xserver-xorg-core 2:1.10.1-1ubuntu1.1 and
