Created attachment 77930 [details] log when weston crashes Using XWayland, if I spawn an X window, say midori and grab its bottom or right border or the bottom right corner and try to resize to a negative dimension (dragging mouse higher or at the left of the top left corner of the X window) lead to a crash. Joining the weston log. Even though I'm compiling weston with -g I can't seem to get a clean backtrace. Some help here please ?
