I can not reproduce this.

Please update to the latest nvidia drivers and retry.

Drivers are up to date(well, now they are anyway... version 419.35). I can reproduce this on two different PCs as well both with same GPU, with today's build as well as builds from few days back.

It's camera clipping settings you are testing, not viewport, right?

@mano-wii @fclem bug or not? Objects that are clipped will not be selectable.
(Which is logical, but perhaps we could exclude the camera from this?)

Cannot reproduce here on macOS 10.14 with integrated intel GPU.

It works in 2.79 as it should. I don't see how this can be considered not to be a bug. Camera clipping itself should be considered a bug. There are no cases where one would need to clip a camera they are viewing things from with itself. If the safe areas and passepartout is visible, the camera border should remain visible as well.

I added a gif showing the problem to the original report. Blender is out of the box, factory settings loaded, drivers are now updated to the newest ones. Problem is definitely there.

Ah yes, I can reproduce it. I was adjusting the viewport clip start, not the camera clip start.

This should fix the problem but it looks like use_clip logic is broken:
