Did you also update intel-dri and/or mesa?

Even qt-diag drops into multisampling -> can you also attach the output of glxinfo?

Does it btw. work on EGL or kwin_gles?

"intel-dri" → what component/package do you mean? Kernel is 3.15-rc8, xf86-video-intel is 2.99.911-r1. I don't know of any other Intel specific DRI components.
Mesa is 10.0.4.

> can you also attach the output of glxinfo?
See below

> Does it btw. work on EGL or kwin_gles?
Will have to rebuild dev-qt/qtgui to build kwin with EGL or GLES2 to test this… will probably get around to do this later today.

Comment 3 Elias Probst 2014-06-09 12:20:05 UTC
Seems this is not strictly a kwin-only issue, but I just had plasmashell crashing as well. Unfortunately it wasn't caught by DrKonqi, so all I have is this line in its journal:

plasmashell: intel_mipmap_tree.c:1541: intel_miptree_make_shareable: Assertion `mt->msaa_layout == INTEL_MSAA_LAYOUT_NONE' failed.

I'm going to upgrade Mesa now to see if this helps, but even if it does, we'd have to make somehow sure other users don't run into the same crashes later again.
Let's see whether the Mesa upgrade helps.

Got it. You probably meant libdrm, which is currently at 2.4.52. Updating now to 2.4.54 as required by the update of Mesa from 10.0.4 to 10.2.0_rc5.
Comment 5 Thomas Lübking 2014-06-09 12:28:52 UTC
intel-dri are the MESA drivers for intel chips (sorry, forgot you're on gentoo - binary distros usually ship them apart), and yes - it's likely a MESA bug ;-)

exposed or triggered by pot. xf86-video-intel or the kernel but it could as well be in Qt/QML

I'll check the glxinfo drawables nevertheless
(fyi, please always _attach_ glxinfo so it's openend in some monospace font ;-)
Comment 6 Elias Probst 2014-06-09 12:59:32 UTC
Created attachment 87088 [details]
glxinfo output

I'm now on Mesa 10.2.0_rc5 and libdrm 2.4.54.
The crash is still there.
Let me know if you need me to provide individual values from a GDB session of the crash.

glxinfo is attached

Comment 7 Thomas Lübking 2014-06-09 13:24:04 UTC
there're matching visuals & fb configs for 24 and 32 bit w/o MSAA in either glxinfo

When you start "kwin --replace" from konsole, there should be some output like

   Drawable visual (depth: foo): 0xbar

what does it say?
Comment 8 Elias Probst 2014-06-09 13:37:03 UTC

Comment 9 Thomas Lübking 2014-06-09 13:44:42 UTC
picks 0xb2 while it should be 0x21

What's very fishy though:
color correction is set to "false", why is it then enabled at startup?
- Did you change the setting?
- What does the GUI say?
Comment 10 Thomas Lübking 2014-06-09 13:45:15 UTC
Should be 0xae - sorry, missed the line.
Comment 11 Elias Probst 2014-06-09 14:24:59 UTC
Ok, didn't think of the color correction to have any effect on this.
I enabled it just for fun but didn't think about it any further.
Now that I disabled it, compositing works just fine.

I hope this helps narrowing down the crash.
Comment 12 Elias Probst 2014-06-18 07:50:27 UTC
Seeing this now also without colorcorrection enabled - back on Mesa 10.0.4. Can't tell right now how the situation looks like with a later Mesa due to a rendering corruption bug in later releases - still need to figure this one out.
Comment 13 Thomas Lübking 2014-06-18 18:59:14 UTC
The *exact* same backtrace? (minus memory positions, of course ;-)
OpenGL 3.1?

From the numerous backtrace I saved during the last days, 4 are MSAA related.
They all end up in:

#8  0x00007fb77d6545f2 in __assert_fail_base (fmt=0x7fb77d78f9a0 "%s%s%s:%u: %s%sAssertion `%s' failed.\n%n", assertion=assertion@entry=0x7fb7649253e8 "mt->msaa_layout == INTEL_MSAA_LAYOUT_NONE", file=file@entry=0x7fb764924e87 "intel_mipmap_tree.c", line=line@entry=1541, function=function@entry=0x7fb764925b20 <__PRETTY_FUNCTION__.26372> "intel_miptree_make_shareable") at assert.c:92
#9  0x00007fb77d6546a2 in __GI___assert_fail (assertion=0x7fb7649253e8 "mt->msaa_layout == INTEL_MSAA_LAYOUT_NONE", file=0x7fb764924e87 "intel_mipmap_tree.c", line=1541, function=0x7fb764925b20 <__PRETTY_FUNCTION__.26372> "intel_miptree_make_shareable") at assert.c:101

I'm not sure whether the difference in the path leading to this is significant.

> OpenGL 3.1?

Forgot to answer this: No, OpenGL 2.0.
IIRC 3.1 didn't properly work on this hardware (Mesa DRI Intel(R) Ivybridge Mobile).

As #334854 is now fixed, I'll upgrade to latest Mesa now again to see how the situation looks there now - whether I still can reproduce this MSAA crashes there.
Comment 16 Thomas Lübking 2014-06-19 12:13:20 UTC
Interestingly http://pastebin.kde.org/pfnuaw9rr/50teqw/raw does not result from "just starting the compositor" but occurs "at runtime" - can you reproduce this with blur & contrast effects disabled?
Comment 17 Thomas Lübking 2014-08-02 06:35:07 UTC
How's the status on this, still crashing?
Tried disabling blur & contrast effects?
Comment 18 Martin Flöser 2015-01-09 08:05:52 UTC
any news?

Haven't seen this crash since months too. Can be closed as well.
