The UI got drunk and flipped some of the elements. I have no idea how to reproduce this. I was using it in a normal manner. When I focused it, it looked like this, and isn't reverting after restart. The link below is a 30 second screengrab and image showing the UI behavior
Edit: Adding screengrab of odd input behavior. Starting the search string with a digit causes it to rearrrange the string, yet it still searches the entered string https://www.screencast.com/t/QDjbfJgo
From the View menu, uncheck Toggle LTR/RTL direction.
Note: This menu item is only shown when the view is mirrored, or you have bi-directional input (a LTR keyboard layout and a RTL keyboard layout installed)
When you have bi-directional input:
Pressing Left Control + Left Shift in the search box will change to the LTR keyboard layout and LTR view.
Pressing Right Control + Right Shift in the search box will change to the RTL keyboard layout and RTL view. -Maybe this was accidentally pressed?
If you are not using the RTL keyboard layout, please consider removing it.
