Description Schlaefer 2020-11-28 09:44:23 UTC 
SUMMARY

Resizing a maximized window crashes kwin wayland.


STEPS TO REPRODUCE

1. Start plasma in a wayland session
2. Activate "Allow resizing maximized windows from window edges" in Settings app > Window Decoration > Breeze > General Tab
3. Maximize an new window with the titlebar button (e.g. Dolphin)
4. Try to resize that window by dragging the resize handle away from the screen edge with the mouse pointer.

OBSERVED RESULT

Kwin immediately crashes:

Process 15507 (kwin_wayland) of user 1000 dumped core.
Stack trace of thread 15507:
#0  0x00007f65effd7615 n/a (n/a + 0x0)

EXPECTED RESULT

The window should be resized without crash.
