Red line in viewport boundries

Hi !
Do anyone of you experienced a red line in your viewport borders?

Thanks :slight_smile:

I have - in V5.


Do you know the meaning of it ?

Nope :grinning: I forgot about the whole thing - I try to use V6 as much as possible…


With all 4 viewports visible move the vertical viewport boundary line and the red line should disappear

I’m dragging the vertical boundary between the Top/Perspective and Front/Right viewports and I’m not seeing what you’re describing.

I’m running a 2017 MBP running Mojave Ac Rhino 5.5.2

I just discovered that closing the right Side Bar makes the red line disappeared.

I have an iMac (Retina 5K, 27-inch, Late 2014) macOS High Sierra.

I was wondering if it was a warning sign . If its just a bug I can live with it :slight_smile:
