gnome shell crashes, dock visible in lookscreen

[Kilian Pfeiffer]

gnome shell sometimes "crashes", especially when system auto locks. The user theme shell extension disappears (standard ui then) and the dock gets partly unresponsive and does not disappear. When the system is locked, the dock is still visible and one can launch programs, which are not visible but still started. Sometimes it seems like two gnome-shell guis are overlapping each other.

I am using a gtk+ theme: https://github.com/nivekxyz/afflatus

There is no crash file for gnome-shell in /var/crash.

Thanks for the bug report.

That is not a "crash". That is a duplicate of bug 1769383.
