LCU Play/Home/Profile/Collection/Loot/Store/RP & IP sometimes disappear

repost from the Client Discussion

I'm sorry I have no idea how to reproduce this bug but it has happened a few times now on different days. I've linked a screenshot of what it looks like.

Re-launching the client fixes the problem but it still randomly occurs nonetheless. If it helps, I do usually leave the LCU idle whether or not it's the active window, for extended periods of time. It's also occurred straight after quitting Spectator Mode.
