My Rhino just updated to 8.4 here and all of my dark mode colors on my custom toolbars also stopped working.
I noticed it at work too but was too busy to reflect on what the reason was. Now I know. 8.3 working. 8.4 not working. So this is a regression bug that was found several weeks ago in a release candidate, but deemed not important enough to fix?
Have to say… with all the problems with this “new” UI in the retail version… feels like I paid for a beta and am being used as a beta tester. Don’t remember moving from V6 to V7 feeling this glitchy.
