When record times are displayed on the left in-game, and any record ghost is visible, there's an option to "Hide PB ghost". This is a separate option to hiding all ghosts, which is done by pressing "G". This option is buggy in a couple of ways.
- If you first display a ghost by pressing the eye icon next to the name, then check "Hide PB ghost", then hide the ghost by pressing the eye icon again, the "Hide PB ghost" checkbox will disappear but it will not be unchecked. This means that your PB ghost is hidden until you view another ghost, and uncheck the "Hide PB ghost" checkbox again. Pressing "G" will not show the ghost.
- If you first display a ghost by pressing the eye icon next to the name, then check "Hide PB ghost", then leave the map, and enter another map, the "Hide PB ghost" checkbox will not be visible but it will not be unchecked. This means that on maps where records are not shown, such as COTD, there is apparently no way to show your PB ghost again until you leave the map, go to a map with visible records, display a ghost by pressing the eye icon next to the name, then unchecked "Hide PB ghost".
In these situations, the UI is often buggy, so you need to click "Hide PB ghost" twice to show your PB ghost again.
