Tester report: the viewer crashes intermittently when changing one of the graphics settings in the Mesh section of Preferences → Graphics.

Known so far:

Intermittent: it doesn't happen on every change.
It isn't known yet which setting in the Mesh section triggers it (e.g. mesh LOD / detail sliders).
Platform and build: unknown yet.

Information to collect:

Which setting was changed, and from what value to what value.
Platform (Windows / Linux), GPU and release tag.
Alchemy.log from the crashing session. On Windows, the crash dump from %LOCALAPPDATA%\CrashDumps (see the AlchemyCrashDumps.reg LocalDumps setup), or the Event Viewer "Application Error" entry.

Likely area: live LOD / mesh setting changes rebuilding geometry while the Vulkan clean pipeline (ingest / mesh store) still references the old data.

Possibly related: #107 (Windows abrupt exit with no dump). Crash dumps for this should be collected per the steps there.

Closing as stale: the report never identified a setting or platform, and the Mesh graphics settings and the renderer behind them have been rewritten since (the old pipeline is retired). If it still happens on the current release, please reopen with the setting you changed and send Help > Report Bug right after the crash.
