[Bug] Crash in desktop RC2 from basic use

I am running the flatpak on Fedora 43. Full output below.

Simplest way to reproduce:
- Create a blank document
- Create a basic shape (like a circle)
- Wiggle the shape around with the mouse for several seconds until the program crashes

Doing any basic set of operations will crash the app eventually, too.

```
$ RUST_BACKTRACE=full flatpak run art.graphite.Graphite

Beginne damit, den Absturz mit dem Fedora 43 Flatpak-Befehl und der Abfolge aus leerem Dokument, einfacher Form und Mausbewegung zu reproduzieren. Untersuche den gemeldeten wgpu 27.0.1 Out of Memory-Pfad und den Rendering-Code, der beim Bewegen der Form erreicht wird; im Bericht wird keine Projektdatei oder kein Test genannt. Erledigt ist die Aufgabe, wenn die grundlegende Interaktion unter dem gemeldeten Setup nicht mehr abstürzt und der Fehler durch eine geeignete Validierung abgedeckt ist.

Vom Indexierungsmodell aus dem Issue-Text verfasst.
