Operating system: Windows 10 64 bit

**Short description of error**
Switching from //Texture Paint// mode to //Object Mode// with an object that has a //Multiresolution// modifier, after sampling and then painting, crashes every time.
This makes Texture Painting with Multires impossible to use.
**Exact steps for others to reproduce the error**
1. Open the file.
2. Press the "S" key while hovering over the object to sample a color.
3. Paint one stroke. (Observe that in the //Image Editor// panel, the wireframe becomes more sparse after the stroke.)
4. Switch to Object Mode. It crashes immediately.
