Compton freezing desktop (seemingly not "-b" related)
Hello, I first posted this on the i3wm issue tracker https://github.com/i3/i3/issues/1720 but it seems to be a compton issue.
i3 version: i3 version 4.10.2-171-ga4fab76 (2015-05-25, branch "makepkg") chromium version: tested dev, continuous and stable OS: Arch Compton: latest git i3 Debug log: http://logs.i3wm.org/logs/5700239927279616.bz2 GPU: nVidia G105M with proprietary drivers
How to reproduce:
On i3wm open a terminal on one workspace (say 1), Chromium (it only seems to happen with Chromium) in another (say 2). Switch forth and back rapidly:
for i in $(seq 1 15000); do i3-msg "workspace back_and_forth" ; done
Description:
There's no graphical reaction (except changing mousepointer) but one can still blindly interact.
I ran compton without "-b" for tests but the same thing happened.
The backtrace I could get is this one:

Is there anything else I can provide?
Your backtrace would be much more useful if you had debugging symbols for Compton. (Notice how the only frames that have names are from the various X libraries.) Is there any chance of your getting them and translating those frame addresses for us?
Yep, I currently keep trying to reproduce but it the error is rather rare. I once could do it but made the mistake of running gdb via the same X that would froze if reproducing was successfull. It seems that the missing "-b" does not fully prevent the problem but at least makes it more rare.
If you can get the debugging symbols that correspond to the exact binary that you used to produce that stacktrace, we can fill in the missing addresses without you managing to catch the bug again!
This is done using the info symbol command in gdb; or, all wrapped up, from your shell:
gdb /path/to/compton -ex "i sy 0x414727" -ex "quit" | tail -n 1
(If you have binutils installed, there is also the addr2line utility, which is probably the best solution.)
Debugging problems with your X environment is always a special sort of frustrating, so thank you for taking the time to report this bug. You might try SSHing in and then using sudo gcore $(pidof compton) (or something similar) to dump a core when you provoke the bug.
Also, you very nicely gave versions for most parts of your environment, but what version/commit of compton are you using?
Finally got it anyway ;-) I this time did not run compton through gdb but just attached gdb to it after it crashed (but still the process not being dead). This is the backtrace:

Using the latest git version (with another commit on my fork but only for the manpage).
Awesome! Two more little favors:
- Can you install debugging symbols for
libxcb? (Might be easiest to just do it for all of the libx* components.) - Is there any chance of getting a core from your X server at the same moment?
libxcb implements the low-level protocol that an application (e.g. compton) uses, though libX11, to speak with the X server. It seems like compton is waiting for a sync fence and never gets the reply that it expects, so it'd be helpful to know how the X server feels about that.
Also, would you mind posting your configuration file and/or command-line options?
Hm, I can try to do so. I'm not that advanced but I will try to figure it out. For the time being, my config:

Additionaly arguments are not used. I will try to get the debugging symbols installed (if you coincidentally use Arch and know how to do that in a short way, perhaps you can save me some time?).
Thanks for looking into this.
EDIT: Seems that there are no debug packages but one needs to recompile them with makepkg options. Will report back after this is done and I could successfully crash it again :P
EDIT2: For all those maybe running into this later on, too: Ok, got the list. The best way to get all those installed is configuring makepkg to use debug flags and then doing
yaourt -Sb $(pacman -Qsq "libx.*" X11 | grep -v lib32)
which will fetch and build all packages that are not lib32 but match libx* and are from X11 that are installed.

EDIT: Seems that I forgot some, will rebuild those too but they do not occure in the BT, so I hope that's of no issue for now.
Now rebuilt all needed packages but the BT itself ofcourse is not different.
On a side note: Does compton crash for you too when you pkill it via tty2 when it's running on tty1?
This isn't the primary issue we're investigating, but I believe that you may have meant to set the backend to "xr_glx_hybrid" instead of "xr_glx_hybird".
I remember there was a typo so it was hybird instead of hybrid, yes. It is fixed now but compatibility is still kept:
// Keep compatibility with an old revision containing a spelling mistake...
if (!strcasecmp(str, "xr_glx_hybird")) {
ps->o.backend = BKEND_XR_GLX_HYBRID;
return true;
}
https://github.com/chjj/compton/blob/master/src/common.h
Aha; thanks for the snippet.
Compton exits normally in response to SIGTERM for me; I tried with my configuration and with a null configuration and the backend set to xr_glx_hybrid.
Like I mentioned, I think the logical next step is to take a look around inside both compton, the X libraries, and the X server.
Most of my systems are Debian-based, so it might be fastest for you to send me the relevant binaries, debugging symbols, and core files; if you have strong objections, you're also welcome to help me reproduce the issue on one of my systems.
I've rebuilt all libX stuff related to X11 and compton using -O0 and some debugging parameters. The thing is that I automated this via the abs (a (BDS)Ports-like system) where you can rebuild the packages from source – but all packaged up and "properly installed" – not binaries flying around. So it would be most convenient for me to just hand you over those pkg.tar.xz-files but they can just easily be extracted so this should be of no issue, I hope. The debugging symbols are not stripped from the binaries. Which core dumps do you need?
And ofcourse I have no objections assisting anyone on trying out Arch to reproduce something (even without the reproducing part) ;-)
The list of libX libraries I've rebuilt:
- libx11
- libxau
- libxaw
- libxcb
- libxcomposite
- libxdamage
- libxdmcp
- libxext
- libxfixes
- libxfont
- libxi
- libxinerama
- libxkbcommon-x11
- libxkbfile
- libxmu
- libxp
- libxpm
- libxrandr
- libxres
- libxss
- libxt
- libxtst
- libxv
- libxvmc
- libxxf86dga
- libxxf86vm
Probably not all relevant. compton is just built using the standard debugging parameters but I can supply you with the binary too, if you want.

Thanks! There isn't any chance, is there, that you also have the core from the X server (e.g. /usr/bin/Xorg) at the same moment? It might be useful (or necessary) to see what the X server thinks the situation is when compton hangs.
Okay, thanks! If I have some time this evening I'll take a look at what you uploaded and see if anything jumps out at me.
Here are the coredumps plus gdb backtrace and a log that I created when I captured the dump because there are many "Memory read failed for ..." lines. X had the pid 412, compton 2520 https://drive.google.com/file/d/0B2gXBp6AAG7fSTdXb0FFVGNHLTg/view?usp=sharing I hope you can find something in there but I'm oblivious. Thanks for any effort.
Hey -- I'm sorry that I've left this so long.
Thanks for being so helpful; I hate to ask for more, but I'm going to need the binaries and debugging symbols that match your coredumps; otherwise the coredumps are hard to inspect!
I thank you for looking into this!
Actually I would wonder if the binaries would not match the coredumps. These are the exact packages I installed. Or did I miss a binary?
Oops; I spaced on the second download link. Thanks for the gentle reminder.
Is there any progress on this issue? I'm getting a similar bug, where sometimes the screen will just freeze, but I can still see the cursor reacting, and can issue commands. Adding --no-fading-openclose to my config fixes this, but then I don't get the nice effects.
@ShirajG Same here. I get random crashes of compton with i3. :( What's the current status of this bug?
And: I've taken another look at the coredumps that @LeonardKoening shared, but I can't seem to load them. Are we sure that they match the compton binary and libraries in those archives?

(*): Shared library is missing debugging information.
The other compton core (core.2520) seems just not to match at all.
Apologies for the delay. My config file:
$ cat .config/compton.conf
# GLX backend
backend = "glx";
glx-no-stencil = true;
# Shadows
shadow = false;
no-dnd-shadow = true;
no-dock-shadow = true;
# Fading
fading = false;
no-fading-openclose = true;
no-fading-destroyed-argb = true;
# When the layout is stacked/tabbed, this enable true transparency
opacity-rule = [
"0:_NET_WM_STATE@:32a *= '_NET_WM_STATE_HIDDEN'"
];
Crashing was getting pretty bad so I had to disable compton and now I am not loading it anymore.
Huh, is that a coincidence that I came here having the same issue 4 hours after you? Well, I can confirm. It happens after I bring up the system after a suspend. It seems to be related to pinentry-gtk which also freezes some functions and hangs the desktop in a similar way when it's window is being displayed somewhere in the background (I use a wm) or a different workspace. Last time (which was like yesterday) I think I fixed the same issue by killing pinentry on a different tty, not sure tho. I don't use compton all the time, I'll run it with debugging when I have some time spare to investigate this issue further.
It seems to be a problem with Firefox for me, at least. I haven't had any issues when it's not open (yet)
Hardware acceleration is on, I'm going to try running Firefox without it and see if it helps.
Everything worked fine until i messed with Xorg
I've got 2 monitors and i was using one xorg-screen and this command to start compton before:
compton --config ~/.config/compton/.compton.conf -b
Then did some changes to my xorg config to set 2 xorg-screens for each monitors, because i was using two graphics cards:
seq 0 1 | xargs -l1 -I@ compton --config ~/.config/compton/.compton.conf -b -d :0.@
Now i'm only using 1 xorg-screen for my monitors, but i wasn't able to put back the first command without getting the freeze issues.
But i fixed the issue by cutting the background flag:
seq 0 1 | xargs -l1 -I@ compton --config ~/.config/compton/.compton.conf -d :0.@
i hope it'll help
Hey my compton config is
basic configuration
backend = "glx";
vsync = "opengl-swc";
glx-copy-from-front = true;
glx-swap-method = 2;
xrender-sync = true;
xrender-sync-fence = true;
# transparancy settings for i3
opacity-rule = [
"0:_NET_WM_STATE@:32a *= '_NET_WM_STATE_HIDDEN'"
];
but i am still facing the issue that when i change workspaces compton draws them over and hangs

I don't think this is being updated anymore. Take a look at https://github.com/yshui/picom
