--- Comment #6 from Adam Fontenot <adam.m.fontenot+...@gmail.com> --- Created attachment 180318 --> https://bugs.kde.org/attachment.cgi?id=180318&action=edit plasmashell crash screencast On my dupe issue, I briefly managed to get this to happen in a reproducible way: 1. Make the preview modal really big for one grouped task icon by opening a lot of windows. 2. Tricking the preview modal for an adjacent task icon to be too big by hovering over the first icon and quickly moving to an adjacent one. (I can reproduce this reliably). 3. Sometimes (?) this will make hovering over the second icon (the one with the tricked preview size) crash plasmashell 3-4 seconds after you hover it. When this starts happening you can reliably crash plasmashell indefinitely by repeating this. Eventually, perhaps after opening and closing some windows, this stops happening again. I suppose I can't prove that (2) is definitely related but it does seem very suspicious in this context. In the original report, activating *any* icon causes the crash. In this followup, it's specifically the icon with the wrong preview modal size. I've attached a screencast of this happening. My dupe issue has an interesting traceback that actually touches a Plasma lib in one place, and that might help someone track this down: Thread 1 (Thread 0x7e2f5a721a40 (LWP 43803)): [KCrash Handler] #4 0x00007e2f5fb7d04e in ???
