BOOM Additional info: Patch is already upstream: https://quickgit.kde.org/?p=kwin.git&a=commit&h=76cd1fdc3411142991096adf8da9d7e74536f671 In fact, it should already be included in 5.4.3... so it's strange that I'm still seeing this crash.
Silly question, after upgrading to 5.4.3, did you restart your session? (if not, that may explain it)
