Arrows for drop-down lists are asymmetrical in most cases (reproduced in special screen resolution). In some circumstances the correct symmetrical arrows are shown.
See the attached video for the following steps
- In the launcher click "Settings". Also works in "Installations", "Skins" or "Patch notes" tabs (does not work in "Play" and "News")
- Move cursor over or click any clickable buttons in the user interface there
- The arrow button becomes symmetrical
The arrows become asymmetrical again when clicking the "Play" tab.
