Bug ID: 419178
Summary: kwin git 9b7ab4d16 segfault-loops on X
Product: kwin
Version: git master
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: core
Assignee: kwin-bugs-n...@kde.org
Reporter: 1i5t5.dun...@cox.net
Target Milestone: ---
kwin (kwin_x11) git 9b7ab4d16 builds but segfault-loops, while the previous
commit 80d3f148e builds and runs fine.
Distro/arch-level: Gentoo/~amd64
Frameworks/plasma version: git master using the gentoo/kde overlay ebuilds
Qt version: 5.14.1
Kernel: Linux 5.6-git (currently rc7+2, commit 979e52ca0)
Graphics environment: xorg-server 1.20.7, mesa 20.0.2
Graphics hardware: AMD Radeon RX 460 (Polaris 11), freedomware drivers
Screen layout: 2 4K TVs as monitors, side-by-side layout for a total 7680x2160
resolution.
Upon reboot and restarting X/plasma (startx with plasma as the session) after
an update, I got the kwin crashed too many times dialog. I don't have any
other window managers installed so there wasn't much to do but rebuild it from
an earlier commit. Fortunately I have ccache setup so the rebuild doesn't take
long. I had updated only a few days previously so there weren't many commits
to bisect and it turned out head (9b7ab4d16) was the culprit.
I normally run an aurora windeco and multi-monitor but tried breeze and single
monitor, but that didn't help. Additionally, I tried suspending compositing,
to no avail. That commit simply won't run.
