System Information
windows7 64
ASUS ATI Radeon HD6870

Blender Version
Broken: (2.71(9337574),2.71.3(ee8dafe),(3d4f540))
Worked: (2.69 and all earlier)

Short description of error
Create any object, uv map with image(maybe without save and creating material)
Create a texture brush(only image or movie) and open(maybe create in blender) any image
Go to tex paint and try to paint anything and when change any of this paramrters

and try to paint again - first draw will working very slow, second and others - working speedly and properly.
if we change any of brush settings - working normal, if we will change any in texture setting(used in this brush)-
wirking with bug.
if we try to do this with other types of textures (not image or movie) - working properly
In all versions earlier than 2.70 - working normal
in 2.70 - whis bug active too, but not so strong(almost imperceptibly)
in 2.69 and all earlier - working normal.

P.S. If i will create texture for brush with animation, Alt+A and try to paint - working properly(update and change is automatic)
If we create image texture with node, and change anything - working normal

Exact steps for others to reproduce the error
open this file, try to paint anything, change any settings of this texture and draw first time - we will see wrry slow working, paint again - working normal tex_paint_change_bug.blend

There's something weird here. Can you try this please? Close the preview of the texture in the properties and try changing the values. Performance won't come back here in that case. Diffirence is imperceptible here but detectable.

closeing preview of brush texture - it is very bad. I close preview, change anything and try to paint - working very slow (not only first time), we have slowly work forever.
select other tex for brush, and select this image again - paint very slow. open preview(maybe close again), try to paint - speed will be normal, change anything again - vorking slovly.
For procedurian textures(not image or movie) - working normal, close or open perview - is not important.

@Psy-Fi, Do you have any news on this? Are you even able to reproduce?

Initially I could see that but only on my home machine. Profiling at the institute didn't show anything though. Let me try it one more time on my machine and if I find nothing let's close.

Closing this, I can't detect any significant difference
