GameTooltip and RMB.
If you hover on unit to see tooltip, when it shows, you click and hold RMB, gametooltip will be always visible(idk its intended or it stuck) and then you move your mouse to another unit, it gonna add id of a new unit to the tooltip and so on until you unhold RMB.
If "Show unit IDs in tooltip" option is disabled then tooltip just stucks w/o adding ids.
To solve it, you gotta unhold RMB and hover on any unit again.
