artem ivanov (ixd) added a comment to T66008: Viewport: edge drawing artefacts (hidden edges are partially visible).

Possible fix: tweaking zoffset value for edges. But there is a tradeoff: the lower the zoffset, the higher the zfighting.
But on the screenshot below (Focal Len 250mm) zfighting artefacts of zoffset = 0.51f is almost the same as with the default 1.0.


With zoffset <= 0.6f and View -> Focal Length = 50 (default) edge artifacts are disappeared for me.

artem ivanov (ixd) added a comment to T59934: Rendering particle object in a hidden collection.

Blender uses Collection, restricting a collection from rendering stops the collection to render even though the collection is added in as particle rendering type

That's true (but I don't think it is a bug).

You can add a common parent collection for collections used solely for particle systems and disable that parent collection in renders (see screenshot).
