When editing a curve and Tab 1 is open, when entering a level on the command line (e.g. 90 @ ... ) the value entered temporarily gets rendered a 'channel' in Tab 1.
Sometimes it appears as a fully rendered channel box (even though nothing is patched), sometimes it appears as an isolated number with a vertical separator to either side.
This is a UX bug only, it doesn't affect operation in any way, just makes you jump slightly when you see the channel view change when editing a curve!
