Blender 2.70
Win 7 64

Open new project
Switch to texture paint
Open 'Texture' tool box and add a new
Open Node editor
Choose texture nodes, the brush ones
Select the 'Texture' texture if it doesn't by itself
Toggle 'Use nodes': it should add a checker pattern

Go back to texture paint mode in 3D viewport
Toggle texture visibility in viewport in the 'Options' tab.

Now the checker texture is visible in the 3D viewport, and is all noisy.
Setting the 'texture brush mapping' to 'stencil' doesn't help.

It does the same with a texture mask by the way, only in BW.

Here is an image:

The same happened with 2.69

Using an image as source in the node editor instead of the checker pattern lead to the image being noisy as well.

The noise has no effect on the painting whatsoever.

@Psy-Fi, mind checking this? Could be something up to threading issued with the texture nodes, but not sure why image will be noisy then.

A little update with that problem.

Have look at this screen capture.

It is obviously 2.70 on my Windows 7 64.

The image used as a texture is noisy too (as was the checker pattern before)
If you look at the texture node editor, the checker should be displayed, not the image.

I found the same behaviour to happen with 2.69.

I use a nVidia GTX 570 card with latest drivers if that may help with the noise glitch.

Tell me if you need the file: it was too big to upload here

This example shows pretty well in which way the image gets distorted: (left: original, right: overlay in viewport)

Note: every time you open the file, the distortion changes slightly.

Thanks willi.

Here is a little video with (maybe) related problems:
https://www.youtube.com/watch?v=hq7y4L8bzyM&feature=youtu.be

And here is the .blend file I've used in the video.
http://glp.lescigales.org/it/blender/Bug%20clone%20paint.blend

There's obviously something wrong in there…

There is also a problem with textures not refreshing in the viewport when using project painting (having to go back to object mode to see the changes) but i couldn't isolate the bug in a small file, so i haven't reported it yet…)

Fantastic, psy-fi. Thanks a lot !

But does this fix also addresses the fact that sometimes the brush texture does not refresh to use what's in the texture node editor ?
This behaviour is to be seen in the video up there (and here:https://www.youtube.com/watch?v=hq7y4L8bzyM&feature=youtu.be)

Or does it fix the noisy texture alone ?
If it's a fix for the noise alone, do you think i should report the non-refreshing texture as a bug as well ?

Thanks for your help !

This should have been fixed in a previous commit. Is it still there?

Oh, sorry then.
In fact I am using official 2.70 as latest build !
I just wanted to make sure that 1. you saw it in the video and 2. to know if you thought i had to report it.

I have tried a buildbot build, but strangely enough it says i am missing some avutil-51.dll

Thanks again !

OK, I just added the missing .dll in blender folder from latest buildbot and it's OK.

Both faulty behaviours have gone, the noise and the nonrefreshing of the texture.
You're a boss !
Both cases completely closed .
