Short description of error
assert hit BLI_assert(elem) when sculpting with dyntopo in debug (lite) build
I've also been getting crash in release build earlier but not very frequently.
Perhaps related T101502: Regression: Artifacts/crash when sculpting with Dyntopo ?
Exact steps for others to reproduce the error
- Open default scene
- Switch to sculpt mode
- Enable Dyntopo
- Attempt to sculpt the cube
