After leaving the launcher screen, the cursor and the selection field don't match. If I want to click on multiplayer, the cursor needs to be on Realms for the multiplayer button to be highlighted. This is also true in the loaded saves and new games. If I'm in game I need to be on the second row of my inventory to select the first row. This applies to all buttons and rows. I can't select the bottom buttons in creating a new world because the mouse won't go far enough below them.  New in 1.14, doesn't appear in previous snapshots, or in Windows 1.14 release.
