The bug

Normally the launcher window remembers its last position and size when closing and reopening it. However, when a game output log window is open and the launcher is closed before that window is closed, it will forget its last position and will appear in the top left corner the next time it is opened.

How to reproduce

1. Go to the launcher settings and check "Open output log when game starts"
2. Move the launcher to the middle of the screen
3. Start any Minecraft version and then stop it again
4. Close the launcher (in case you have "Keep the launcher open while games are running" checked)
5. Close the game output log window
6. Reopen the launcher
   It is in the top left corner of the screen
