Looks like this crash in libnvidia-glcore is triggered by QtQuick. I don't see how it can be fixed or worked around in KWin. @David Shall we close this bug report?

>@David Shall we close this bug report? I would rather not till we can make a valid report to Qt. Also given we're using the much lower level QQuickRenderControl it could very well mean we're the ones at fault. There's a reasonable chance that my rewrite of Aurorae to EffectQuickView will have fixed things.

Can everyone in this thread confirm which window decoration they are using? Also that it crashes when they visit this webpage: https://www.youtube.com/results?search_query=%F0%9F%98%80 which puts an emoticon in the window titlebar.
Git commit 39798bffb1398d6b75a067ff5552a63ea6b182f7 by David Edmundson. Committed on 19/02/2020 at 08:27. Pushed by davidedmundson into branch 'Plasma/5.18'. [plastik] Disable problematic text hints Summary: Use of "style: Text.Raised" combined with UTF-8 emoji characters currently crashes deep in font rendering code. A report has been submitted upstream: https://bugreports.qt.io/browse/QTBUG-82311 Given this crash is surprisingly common, this patch removes the text shadow. I normally would be against removing features, but this was a subtle effect anyway and frankly just made things look blurry. I doubt it'll be missed.
