Cannot confirm that with our latest master, please always try the latest build from our buildbot before making a report.

I couldn't reproduce this in 2.77a either.

If it still happens with latest builds we're going to need a .blend file. At least the screenshot shows some non-default settings (GLSL, Textured Solid) beyond what is described in the report, and there could be more differences that cause this specific problem to happen.

As far as I know, most problems with updating diffuse colors in 3D View were fixed in latest builds except the one in Sculpt mode, it was reported by me in #48788 which is in a waiting queue.
Edit: just in case I've checked out the latest build and found out that while in Textured Solid or Textured mode (Multitexture version), specular color and intensity are showing up correctly in Edit Mode, but always displayed as white in Object and Sculpt modes. Material's Shadeless option also works only in Edit Mode. Here is how it looks on my side:

You can use my test file to compare: 3DView_Textured_Specular_and_Shadeless.blend

This issue is supposed to be fixed by adfd58a. If it's still a problem after that commit, please report back.

Tested 50a44ed and compared it to cf53389 in terms of speed, I have used Textured Solid mode and Multires plane with 10 subdivs (1 million polygons) and plain diffuse color. There is some slowdown in viewport and sculpting performance in Sculpt mode, but it doesn’t feel like a critical hit. Well, at least now it's possible to see diffuse colors with Multires. Colors themselves seems to be updating properly now.

@SpectreFirst, can you check if the speed is the same as 2.77a? If it is, i would propose to leave thing as is for 2.78 and dig into more tricky solutions here after the release (it's a bit too close to the release now to start doing biig changes in areas like viewport, and the current code should be the same as in previous release).

Sure. Tested 2.77a abf6f08 and latest 2.77.3 50a44ed: viewport in 2.77a feels a bit faster for some reason, but difference is not very noticeable and those who work in 2.77a probably won’t notice it at all. Sculpting performance feels about the same so I don’t think most people will notice any changes compared to 2.77a. Overall performance feels to be about the same so I don’t think this optimization is critical and probably should be left safely for the next iteration. I would prefer to fix specular highlights instead. I will form another report for that purpose.

Ok, good to know.

And yes, please open a separate report for specular, would help us to keep track of the things :)
