Same here, already reported. Working with big SubD and moving control points randomly put cpu to 100% load forever or even crashes.
- Eye Hurting Icons! seems recent, I’m on a FHD or UHD so I can’t see problems , but others can.
- Selection Highlight bug this still happens
- Unselecting completely selected SubD crash rhino - #4 by maje90 still happens if you wholly select 2 subd objects
- Rhino 8 User Interface Freeze Approaches - #47 by maje90 detaching toolbars still results in random sizes, even if you carefully correct them as you need (and the rest of that thread have lots of problems… all fixed?)
- Toolbar buttons require an extra click
- WIP (8) feedback - #42 by maje90 (.gif) UI hiccups while resizing UI (taskmanager sees ghost process appear/disappear, same in windows bottom bar)
- Tried WIP since months - #50 by maje90 curvature graph on whole SubD is a joke. I’m still using extract edge + history, losting your neat addition of having hairs be always normal to surface on subds
. Do you guys try rhino while developing it? Working with SubD with 1k faces is absolutely normal here. Curvature graph on ALL edges is no-go. Com’on… - Tried WIP since months - #40 by gustojunk tool to detect double-concave areas? It’s 2023.
- leopard analysis? ^
- WIP (8) feedback - #40 by maje90 most of the problems in the video, still there
- WIP (8) feedback - #36 by maje90 SubD methods are still completely lacking. Almost inaccessible type of geometry. Best solution is still to cast it to mesh and work there, losing lot of informations.
- WISH: more coherent face/edge selection displaying - #12 by Gijs still unchanged
- WISH: specialized gumball for control points editing control points is still a punishment. Related > Rhino8 WIP - Gumball
- Control points and net fully visible when draft angle on - #5 by maje90 absolutely nonsensical situation, but no change
Who works with subd globally get a feeling to be left behind from devs. No rhinocommon improvment. G1xx is cool, but please don’t stop. What about custom face-packing while ToNurbs?
- Analysis tools windows/docking rework probably pushed to RH9 , or simply forgotten/ignored/unseen … ok, but at least make the floating windows of analysis tool a little more “serious” … currently they open with random sizes.
The fear is that you guys will slow down developing/fixing after release (as with any other software house), or start pushing “the fixes” on the newly WIP/9 version.
If you actually plan to not slow down about those matters and to achieve them for RH8, you could’ve release 8 months ago (I’m ready to pay!)
… but I suspect it’s more complex than this.
As always I surely look pedant and salty, but I love Rhino and McNeel staff! Thank you for the great work! 
Looking forward Rhino 8 release.
