SUMMARY I was working in Wayland session and when I clicked on an icon in taskbar, whole session crashed (taskbar disappeared) and almost all applications were close. However some continued to run (I remember Firefox and Evolution). When I looked at journalctl, I only found these messages around the time of crash: sep 06 15:45:44 xcxcx600 plasmashell[1363]: kf.plasma.quick: Couldn't create KWindowShadow for ToolTipDialog(0x5641e98822c0) sep 06 15:45:44 xcxcx600 plasmashell[1363]: kf.plasma.quick: Couldn't create KWindowShadow for ToolTipDialog(0x5641e98822c0) sep 06 15:45:44 xcxcx600 plasmashell[1363]: kf.plasma.quick: Couldn't create KWindowShadow for ToolTipDialog(0x5641e98822c0) sep 06 15:45:44 xcxcx600 kdeinit5[1483]: kdeinit5: Fatal IO error: client killed sep 06 15:45:44 xcxcx600 xembedsniproxy[1392]: The X11 connection broke (error 1).

I have attached 2 backtraces. If I remember correctly both cause crashed like I described.
@Nate As far as I can tell, both backtraces are for plasmashell, not kwin_wayland. Maybe the product should be changed to plasmashell?
Anytime there is a full session crash, it's because kwin_wayland crashed. When this happens, all apps die as well, which many people misinterpret as the cause when in fact that is a sympton of the KWin crash. We need a backtrace for kwin_wayland in order for the crash report to be actionable.
We still need a kwin_wayland backtrace.
