Mip-mapping?

I noticed that in my cockpit-based game, at about 40cm on front of the camera the textures make an obvious little "pop" to a more blurry version as the camera moves further away.

Is this a change in mipmap level? Unfortunately it occurs right at the distance my central control panel is placed at, so small head movements cause the issue to be easily seen.

I also see the quality of shadow edges take a bit of a nosedive at that distance too, going from very sharp to quite blurry.

Any suggestions on mitigating these effects?
