Hey, thanks for the detailed report. This is a known bug in v2.6.20 that affects the vertical activity bar. A few users have already reported the same thing:
- Interface bug, extra color area
- Sidepanel position issue (empty gap at the bottom) when Activity Bar is set to vertical mode
The team is aware. A fix should come in the next update. I’ll close this thread as a duplicate so the discussion stays in one place.
