-- Information about the crash:
I was working with Obsidian (an Electron app) on one of my 12 virtual workspaces. It was pinned to all workspaces. I used a keyboard shortcut to move it to a different workspace that I hadn't active at the time. Then KWin crashed. Most applications crashed with it, only KWrite and Dolphin and Konsole stayed open.

The reporter is unsure if this crash is reproducible.
