Blender Version
Broken: current master e53c00a

Short description of error
Rotating the view (middle-click and drag) in a 3D viewport, while the "Viewport Shading" is set to "Rendered" yields wrong texture coordinates if the texture slot uses "Object" coordinate mapping.

Exact steps for others to reproduce the error
Open mapping_bug_object.blend.
Change "Viewport Shading" to "Rendered".
Notice that texture mapping on object "Plane" is wrong.
Press F12 to render scene.
Notice that texture mapping is correct in rendered image.
Press Escape.
Notice that viewport is now updated to correct texture coordinates.

I don't really see an issue with the mapping. And there's no difference in the viewport before and after the render.

What exactly do you mean "wrong"? Maybe some screenshots will help here.

I'm sorry, the steps to reproduce this bug weren't clear.

It happens while rotating the view in the 3D viewport, while "Viewport Shading" is set to "Rendered".

Before rotation:

After rotation:

Hello. I checked this bug report with the current official 2.71 Win64bit version and the attached test file works as expected in both Blender Internal and Cycles.

That's weird, because don't remember fixes in that area.. Would have a closer look. Also, do you mind checking latest builds from builder.blender.org?

Sergey, I downloaded the latest build from b.b.o., Blender 2.71.0 (Hash: 5588e45 dated 2014-06-30 01:55) Win64bit (blender-2.71-5588e45-win64.zip) and I can confirm that the behaviour is correct in both BI and Cycles. The issue raised by der_fab happened only in BI because I forgot initially to assign a target Object in the Texture|Mapping|Object field (which is the Plane itself).

I have also downloaded the currently available 32bit verions (Hash: ea3c2eb dated 2014-06-30 00:42) and as far I can see it works fine also here.

Indeed, the bug seems to be fixed. I tried bd777ff dated 2014-06-27.

Closing then, no need to keep invalid bug reports open! :)
