If I start SE, it will reopen my windows of the previously opened workspace, but it appears to stubbornly force the view such that the "remembered" cursor is 6 characters from the right.
I've been working around this by using the vim emulation '^' to shift the window back to normal. I've seen this when I other workspaces while SE is running (and switching back can spuriously exhibit this issue). The cursor position is in the correct last remembered location, but the window view always forces the cursor to position 6 so it's all shifted weird. I've even resorted to exporting my options, blowing away my 23.0.1 config directory and reimporting my options (attached), but it crops up after a few sessions.
