I've created a simple blender file with a plane and a material assigned to it with a texture. I've then animated the 'offset' material mapping property of the texture. Finally, I put the 3d view into Material mode. When I play back the animation, the display in the 3D view is not updated to reflect the animating offset value. This makes it difficult to animate this property correctly, since you cannot get visual feedback during editing.

If you manually adjust the offset or manually adjust another property that causes the texture to update itself, then the 3d view updates to show the appropriate offset. Also, the correct texturing is shown for rendered images.

Not sure why there was a crash. I've created another file that demonstrates the problem. Open it and press play. I would expect to see the texture animating in the viewport, however the 3d view does not update. If you stop and then manually adjust the Texture in the properties panel by adjusting any of it's other values, the 3d view will update and display as expected.

This problem also occurs when animating the mapping scale property of the texture.

Sorry, the new attached file cannot open, too.
What is Viewport Shading set in with the file?
A latest buildbot build version has this bug .

In both cases the viewport shading is set to Material. It needs to be in this mode to demonstrate the bug.

Please try a latest build from https://builder.blender.org/download/ (Not Gooseberry)

Also try saving your file in solid view and we will switch to material view on our end
