Bug ID: 464621
Summary: SIGSEGV (stack overflow?) when resizing quicktiled
window rapidly
Classification: Plasma
Product: kwin
Version: 5.26.90
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: ar...@aarsen.me
Target Milestone: ---
KWin crashes on what appears to be a stack overflow when rapidly resizing a
quicktiled window.
I can reproduce this crash in a nested Wayland session (open one, run
WAYLAND_DISPLAY=wayland-1 kinfocenter, tile kinfocenter, rapidly move the top
edge).
I haven't had time to attempt to reproduce this bug on master, nor to build the
debug infof or the functions in the trace below without it. Apologies about
that!
STEPS TO REPRODUCE
1. Tile a window to a bottom corner
2. Resize it vertically really quickly
3. Observe the crash
OBSERVED RESULT
KWin crashes on what appears to be a stack overflow
EXPECTED RESULT
KWin does not crash
