I'm having inconsistent behavior trying to select grains and particles, but not vertices on geo. I can't consistently box select. It works about 5% of the time.

I've got an Nvidia GeForce GTX 1080.

Driver version is 23.21.13.915, which seems weird to me. I thought they wer ein the high 300's now. That looks like an i.p. address
- LOL.

The OS is Win 10. I tried rebooting.

I'm also having issues where I dive into or out of a node and the points do not display. I have to jump around a bit more and then they'll appear.

Sometimes my grain pile is black, in the viewport, like a holdout, and sometimes they're there, but not really there. This is starting to feel like a graphics card issue.

Needless to say this is decreasing my productivity. Any advice?

New graphics card driver was installed. Still not working correctly.

How is selecting grains in the scene view supposed to work? I'm trying at home in Centos 7, with an Nvidia GTX 970, driver version 384.111.

The best I can get is this:

1) create a cube of grains and simulate a few frames.

2) box select some grains in wireframe view. All of the grains disappear.

3) toggle shaded mode on and off. All of the grains become visible again, and the selected wireframe grains are now yellow.

4) Try to select any other grains. Impossible.

5) advance a frame in the simulation, and you can go back to step 2.

This is the experience on Centos 7. In Windows 10 it's much more erratic for me.

Can someone please test this? Am I going crazy?
