What just happened?

Building and panning the camera around, with the whole linked object selected, comprised of meshes and prims.

What were you doing when it happened?

When building, with an object comprised of multiple prims selected, when panning the camera around, the selection seems to disappear from some areas.

The issue seems to prefer to happen on linksets with meshes in them.

What were you expecting to happen instead?

I expected the highlighted prims not to become randomly and intermittently highlighted.

Other information

I've attached a couple of pictures to illustrate it. The first one has the whole object simply selected, the second one is when you start to pan around and some outlines disappear.

I couldn't find the exact object shown in the images, but I found a similar one at http://maps.secondlife.com/secondlife/Clockwork/157/212/1711 that seems to reproduce the issue.
I can only reproduce it when panning around the object with "Show Hidden selections" enabled and when panning using ALT+click+ drag, not when panning around using the Camera tools orbit.

It repros on my system when ALM is enabled and disabled.
Also repros when Object Object Occlusion is enabled & disabled.

Bug does NOT reproduce on Second Life 5.1.3.514233 (64bit): http://wiki.secondlife.com/wiki/Release_Notes/Second_Life_Release/5.1.3.514233
No repro on this build: https://gyazo.com/c8fb71096a42e6068bfbe92a5af42f9f

I presume this is caused by the selection outline changes in "Love Me Render"
