While modifying the effects settings, the app froze and eventually dumped core:

file:///home/cowens/src/cool-old-term/app/SettingsEffectsTab.qml:56:13: QML CheckableSlider: Binding loop detected for property "value"
qmlscene: ../../src/xcb_conn.c:186: write_vec: Assertion `!c->out.queue_len' failed.
./cool-old-term: line 4: 1178 Aborted (core dumped) qmlscene -I imports app/main.qml

I believe I had just enabled screen distortion and was attempting to increase bloom.

I think this might be due to hardcoded values in shaders that require the shader to be recompiled at every update of the value. I will try to propose a patch. Does this happen often?

I just pushed a new version which should fix the issue. Test that and let me know please.

Hello everyone, a recent bump in the issues has brought me to analyze this a bit. After some research it seems that this is an issue related to Qt and/or libxcb. It has been reported many times it seems to be fixed with Qt 5.3 and newer version of libxcb. Which system are you guys running? Can you test it again on upstream Qt and newer version of libxcb?

I can confirm this. Qt 5.3 on Ubuntu 14.04 resolve issue.

I recompiled Ubuntu's libxcb with this patch: http://cgit.freedesktop.org/xcb/libxcb/commit/src/xcb_out.c?id=be0fe56c3bcad5124dcc6c47a2fad01acd16f71a and that fixed my problem.
