            Bug ID: 479859
           Summary: select-and-drag text crashes some or all non-KDE apps
                    in wayland
    Classification: Plasma
           Product: kwin
           Version: 5.27.10
          Platform: Gentoo Packages
                OS: Linux
            Status: REPORTED
          Severity: major
          Priority: NOR
         Component: wayland-generic
          Assignee: kwin-bugs-n...@kde.org
          Reporter: k...@kaishome.de
  Target Milestone: ---

SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***


STEPS TO REPRODUCE
1. Browse a web page in Chrome
2. Select text with the mouse
3. Try to drag the selected text across the screen

OBSERVED RESULT

The desktop freezes for a short amount of time ramping up IO, then the
application (source of the drag operation) crashes.

EXPECTED RESULT

The application should not crash, obviously. But also, I should be able to drag
the text to another window, or drag the text from one input field to another.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Gentoo Linux 2.14, kernel 6.6.9, Wayland
(available in About System)
KDE Plasma Version: 5.27.10
KDE Frameworks Version: 5.113.0
Qt Version: 5.15.11

ADDITIONAL INFORMATION

If this happens by accident, unsaved work gets lost thus raising bug priority.

Also, this or a similar crash happens when dragging the last open Chrome tab
out of its window.

Apps that actually drag text as text seem to not be affected, e.g. I could drag
text from Sublime Text to KWrite. So this may be limited to the Chrome-family
of browsers and Electron apps. Or there is an issue with multi-format clipboard
contents, e.g. dragging text from the browser can insert HTML and plain text,
or dragging a browser tab can insert the tab in another browser or the URL in a
text editor.

Chrome creates a crashdump with SIGTRAP, but there's no backtrace.

No such crash seems to occur with X11.
