Bug ID: 495317
Summary: 0d7bca07b920319a18007aa6a599f664236b3cc6 makes
kwin_wayland crash when hovering over Task Manager
tasks
Classification: Plasma
Product: kwin
Version: master
Platform: Other
OS: Linux
Status: REPORTED
Keywords: regression
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: n...@kde.org
CC: notm...@gmail.com
Target Milestone: ---
100% reproducible for me; just hover over a Task Manager task:
#11 QString::QString (this=0x7ffc13c4d9c0, other=...) at
/usr/include/qt6/QtCore/qstring.h:1186
#12 KWin::Window::desktopFileName (this=0x31a257e0) at
/home/nate/kde/src/kwin/src/window.h:1241
#13 KWin::ScreencastManager::streamWindow
(this=0x3070f150, waylandStream=0x31253aa0, winid=<optimized out>,
mode=KWin::ScreencastV1Interface::Hidden) at
/home/nate/kde/src/kwin/src/plugins/screencast/screencastmanager.cpp:50
`git bisect` says it was this commit:
0d7bca07b920319a18007aa6a599f664236b3cc6 is the first bad commit
commit 0d7bca07b920319a18007aa6a599f664236b3cc6

Double buffer m_tile
Add a new m_requestedTile member that gets set immediately
with either requestTile() or setQuickTileMode(), at
XdgToplevelWindow::handleStatesAcknowledged()
Window::commitTile() will be called and m_tile will be actually
set only on that step
Going back to 649b3df296cbcae2dce21fbb555ee3796e4e543e (the immediately
preceding commit) makes the crash go away.
