Short description of error
Glitches in viewport in wireframe mode

Exact steps for others to reproduce the error

  • Subdivide default cube with 100 cuts
  • Return to object mode
  • Deselect the cube
  • Activate X-Ray (more than zero) and Activate Viewport Anti-Aliasing (5 Samples or more)

If you don't see the problem toggle shading between solid and wire

The problem disappear when Viewport Anti-Aliasing set to No or Single Anti-Aliasing


For a heavier file check 01.anim.blend from the dweebs and go on wireframe mode.

I don't know what to look for. I don't see any problem:

to see the artifacts you need to : first back to Object Mode then deselect the model .
the artifact gone when selecting any object . if the artifact disappear toggle shading mod between solid and wire.
this cube is subdivided with 100 cuts and

I still can't reproduce the problem.
But by the image, there is really something strange there.

xray 0- 0.99


xray value 1 solves the problem

I will keep this opens since the sample file is simpler.

Played with a heavier file and it seems to only affect occluded faces or something with depth.
Also changing wireframe in Viewport doesent change anything only Xray value 1 in Viewport Shading solves it.

Or if you set your user prefs Viewport Anti-aliasing to no Aliasing


(probably workbench refractor releated?)

Edit: it seems also to affect not occluded faces far away from viewport as you can see here:

This looks similar to T75063 which appears to be fixed now, can anyone confirm?

With the last branch it is More better , but the problem still with heavy scenes . to see the problem in a default cube : make a duplicate the subdivide it 100 cuts
