Strange flickering while modeling in Blender 2.8 beta So, while modeling simple building, I came across some strangle flickering on faces, which is strange for me.
There is no overlapping, so "z-fight" is not the cause here.
Flickering is visible with solid or rendered -- no matter which.

I have blender 2.8 beta by 27.02.2019 version

I inserted images and .blend file, so please look at them :)
The flickering was because your Clip Start distance was way to small. This setting can be found in the View menu of the Properties side panel. The N key to toggle view or hide panel.  

It was set at 0.00002m :


Increasing the distance a little to 0.1m .........
