Don't know if this is in the tool department or UI department. So I'll assign you because I'm guessing this is the UI and not tool specific.

This is the solution that came to my mind (but I did not consider all cases):

diff --git a/source/blender/draw/intern/draw_cache_impl_mesh.c b/source/blender/draw/intern/draw_cache_impl_mesh.c

Hello ,
I did short video compare between 2.79 and 2.8 for Mesh Circle Curve how its work during in subdivision modifier smooth and quad toggle in 2.79 its work fine smooth toggle but in 2.8 still not work in smooth toggle in edit mode .
Please check video example.
Thank you.
Regards.

@Clément Foucault (fclem), actually, i am not sure what's going on there. As for subdiv modifier i generate all edges and set the render flag. Mind having a loot and tell if it's anything specific draw manager is missing? Or maybe it's something totally in the control of draw manager?

Well, not sure why one would expect bug to be fixed in the nightly builds, the report is still marked as Open.. We fix bugs as soon as time frame allows us. Is not like we don't fix them to keep artists unhappy. But keep in mind, we've got 100 times more open reports than developers dealing with those..
Bit of patience, my friend ;)

It's a good suggestion, ideally we'd support one set of seams per UV map. However it's outside the scope of the bug tracker, see here for these types of suggestions:

Confirmed for meshes without faces.

In Edit Mode when i want to Mesh curve circle segments make smooth with using modifier - subdivision surface , its not be in smooth toggle like 2.79 . Please can fix this bug . Thank you. Regards. Pierre

Sounds more like a duplicate of this one: https://developer.blender.org/T57770
And that has been resolved.
Please check if it still happens with latest builds.

eh, looks like this has been broken in master too, and since at least 2.78! Odd this never got reported :/

You need to specify at least the blender build hash and also build date. These are available on the splash screen.

Woo woo!
Closing

yes - it worked,thank you

i will check now

It looks like you need OpenGL Depth Picking turned on if you want OpenGL Select

@Sergey Sharybin (sergey) this file is much faster to crash reliably here (see weirdness 1 for instructions). It seems the same error as T58893.
Here at some point I got data llocated by T.17, freed by T.12, and with a read error by T.16,

I managed to reproduce a crash. Assuming is the originally reported:

@Campbell Barton (campbellbarton) I have a .blend file in this issue that make it really easy to reproduce: T58849

Yes, I see the problem. You can work around it by turning off the 'Loop Slide' option.
There's some complicated optimization that goes on to try to even out the loops when loop slide is on, and looks like there might be a bug in that.

Can confirm

Just an update. I've tried with the latest alpha 2 build and all 2.8 beta builds after 925380050d0 and the bug hasn't been fixed.
