Trace

https://pastebin.com/cN5mMthk

Steps of reproduction

1. "compton &" in bash
2. after some time realising that the effects don't work, terminal output is:

compton: ../compton/src/win.c:1623: map_win: Assertion `!win_is_focused_real(ps, w)' failed.

[1]  + 3362 abort (core dumped)  compton

What's stack trace, and where's the dump?

[yshui]

Is that the only terminal output?

How often does this happen?

[xt1zer]

Is that the only terminal output?

How often does this happen?

Yes. Each time after, like, 3 minutes after launch

[yshui]

Can you run compton --log-level=trace and post the output?

[xt1zer]

Can you run compton --log-level=trace and post the output?

This takes longer that I expect it to, I'll write back when it happens next time with a log

[xt1zer]

Surprisingly, it never crashed since your response. I'll try to reproduce the issue with active and daemon (compton -b) processes

[xt1zer]

Can you run compton --log-level=trace and post the output?

Hey, I figured out that it at least crashes when a "Download" popup window of Firefox appears (floating), this happened now a few times. OP updated with the trace

[sveatlo]

I have exactly the same problem on arch with i3-gaps, but I cannot reproduce the bug with firefox's "Download" popup window or any other floating window.

This is my terminal output without trace log level:

[ 03/25/2019 14:38:58.307 glx_bind_pixmap ERROR ] Failed to query info of pixmap 0x04e2ea7e.

[yshui]

@sveatlo Can you try again with --log-level=trace? Thanks.

[sveatlo]

I was just about to post it :D https://termbin.com/k3sh

[sveatlo]

also my config (very simple):

shadow = false;

inactive-dim = 0.3;
inactive-dim-fixed = true;

backend = "glx"
mark-wmwin-focused = true;
mark-ovredir-focused = true;
use-ewmh-active-win = true;

refresh-rate = 0;
vsync = true;
dbe = false;

detect-transient = true;
detect-client-leader = true;
invert-color-include = [ ];

glx-copy-from-front = false;

[yshui]

@sveatlo @xt1zer Should be fixed in next (also in stable/6)

[yshui]

Can you confirm?

[sveatlo]

I've been running from a git build since your comment without any problems. Though I wasn't able to forcefully replicate the issue before, I believe it is solved.

[yshui]

I'm closing this then. Please reopen if it happens again

[xt1zer]

I'm closing this then. Please reopen if it happens again

Oh hey, I wasn't home til now. By "confirm" did you mean if the commit fixed the issue? When should I expect an update in Arch repos?

[clawoflight]

Can you release a new version, since this fixes a deal-braking bug?

[yshui]

@clawoflight I don't understand how this is deal-breaking. Distros shouldn't be using debug build, and release builds shouldn't include asserts.

[yshui]

ping @xyproto.

Is ArchLinux not doing release builds of compton?

[clawoflight]

@yshui doesn't look like it is using debug builds:
https://git.archlinux.org/svntogit/community.git/tree/trunk/PKGBUILD?h=packages/compton

And this is the meson wrapper:

https://git.archlinux.org/svntogit/packages.git/tree/trunk/arch-meson?h=packages/meson

[yshui]

@clawoflight the meson wrapper uses --buildtype plain and does not enable b_ndebug. So that's why.

cc @xyproto

[clawoflight]

Thanks for the replies! I opened a bug on the Arch side: https://bugs.archlinux.org/task/62166

Just received an update and the issue seemed to never appear again. Thanks for your support!
