Bug report #13658
Polygons disappear after saving

I have update some weeks ago to 2.10 Pisa and when I started using it heavily in the last week, I encounter regular this issue: after saving the shape file, especially when qGIS has been running for some while or when many adaptations to the shape file have been made (memory related?) certain polygons (in the vicinity of the canvas I was working on) disappear from the screen. The label is shown on top of the location of an adjacent polygon.
The original polygon is still in the table list, however when you select them, the adjacent polygon that also shows the label is lighted up. Only solution is to delete the affected polygon from the table, restarting qGIS, and start redrawing. This happened now 20-30 times.
Please let me know what I can do.

I met a similar problem but I couldn't replicate it:
I created a point in a shapefile and set its attributes. As I saved the edits, the point disappeared.
I was working on a shapefile with EPSG:4327 while the map was set with EPSG:3857 (on the fly reprojection activated).
QGIS 2.10 (32 bit) on Windows 7.

Update: With swisstopo's REFRAME (easily reproducable: http://www.swisstopo.admin.ch/internet/swisstopo/de/home/apps/calc/reframe.html) reprojected shapefiles appear to be empty in QGIS 2.12 (Win 7, 32/64bit). When I save the reprojected shapefile in another file with the old ArcMap we have here, all features reappear. This is most likely the same issue as described above.
