I started just now to use a temporary scratch layer for digitizing features: in detail I need to split an existing layer of polygons in subregions, according to a raster level.
I succesfully copied the existing features in temporary layer, saving it as shapefile seems ok. After splitting one geometry in different subregion, trying to save as ESRi shapefile lead to an error
"Error: Feature write errors:
Feature geometry not imported (OGR error: )"
And opening the shapefile shows the previously splitted geometries with vertices coordinates mismatch.
Replicated with Alaska sample data "lakes.shp" Open, add, new temporary scratch layer, copy geometries from lakes, split save as ESRI Shapefile.
Corrupted layer and screenshot attached.

Maybe GDAL is outdated?

Hello,
Now it works, don't know if is a gdal related problem or was fixed in new version
I have updated to Debian testing cause I was looking for GDAl 2.1 and geopackage support. Then I have compiled GDAL 2.1.2 for MDB support.
Now with Alaska data set, after splitting the geometry and save to ESRI shapefile there's no error and the resulting shapefile seems OK in QGIS.
