Selection Highlight bug

Aaaand another one:
If sub-object is enabled (or by using CTRL+SHIFT) and you fully select everything of a SubD object, other meshed geometries will randomly be colored yellow (as if selected), but no effect other than this:

Is it useful to flood the forum with reports of bugs like this?

I’m seeing this as well!

Thanks @maje90 I’ve added RH-73336 Highlight glitch


  • open WIP
  • right click > shaded on perspective viewport
  • creating 2 subd cubes
  • fully selecting (CRTL+SHIFT+cross window) one cube make the other become yellow too

Creation order (or screen Z depth order) is related to which othe subd object is turning yellow.
Playing to trigger this bug also trigger this

I can’t repeat this issue. Does this happen also without the 3d connection mouse in use?

pls send _SystemInfo

Yes, USB not plugged before starting WIP.
