- 3D View: Disabled surface texture appears in 3D PDF export
- 3D View: Title angle does not rotate title text
- Contents: Undo deletion: layers from different maps are selected in Contents
- Crash after creating 3D view
- Crash when closing Surfer after printing
- Crash when importing multiple files
- Crash when opening an empty PDF file to Surfer
- Double click on BAS opens empty Scripter
- EMF export: Rotated text exports as polygons/polylines for certain degrees of rotation
- Internal Error (cacheejectionlru.cpp)

- Internal Error after creating 3D Surface map (graphics3.cpp)
- Internal Error after exporting the 3D View to 3D (stratosstatemanager.cpp)
- Internal Error in 3D view with Walk (statepresenter.cpp)
- Internal Error when cancelling 3D View flythrough (grid.cpp)
- Internal Error when closing Surfer (autodocuments.cpp)
