Description Ladislav Zitka 2018-10-29 05:46:17 UTC

SUMMARY


STEPS TO REPRODUCE
1. Connect external monitor via USB-C
2. Let spectacle main window be located on either primary or secondary screen
3. Click "Take a New Screenshot"

OBSERVED RESULT
Spectacle just shutdown silently. There is no error visible in Xorg.0.log neither in messages. But I see in dmesg output:
[ 1256.092610] spectacle[22229]: segfault at 68 ip 00007fc5650e2d1b sp 00007ffe65f637c0 error 4 in i965_dri.so[7fc564cd2000+7ef000]


EXPECTED RESULT


SOFTWARE VERSIONS
(available in About System)
KDE Plasma Version: 5.13.5 (-r3 but I think it is internal Gentoo patch release)
KDE Frameworks Version: 5.50.0
Qt Version: 5.11.1

ADDITIONAL INFORMATION
I am just enabling debugging on Gentoo box (must recompile glibc as well) to get some more valuable data.

I have found this could be issue with /usr/lib64/dri/i965_dri.so (as per error) which is lib from mesa, I found some reports regarding segmentation faults related to specific versions.

I am now on stable mesa in Gentoo, but will try to upgrade:

Thanks, it sounds like this is way below us. Please report this to the Mesa devs, especially if it's 100% reproducible. Thanks again!
