I noticed that if I open an incognito tab in Chrome or Firefox and load donationcoder.com then the main page loads as http (not https). While loaded as http Chrome labels the connection "Not secure" and some of the top menu bar icons are not visible. Once any link on the page is pressed the https version is loaded.

If this only happens in the newest FARR version then it is probably an issue that mouser will fix.

In the meantime you could try some workarounds:

First, check if you can move the FARR window using the Win + Shift + Left/Right shortcuts in Windows. Those shortcuts work on most windows. Did not work on my FARR though, but worth a first try.

Alternatively, try using an AutoHotkey script to move the window to the visible part of the screen. One single line of code is enough to move the FARR window to near the middle of the primary display on my PC.

If that works then you could for convenience make a FARR alias to run the script when you type "move".
alias name: move FARR
regex: ^move$
Result: dolaunch C:\folder\moveFARR.ahk

Modify the result line to the filename and folder you want for the AutoHotkey script.
You could also change the "move" part of the regex to whatever other string you want to use to launch the script.

I suggest Ctrl+Space or Alt+Space. Both very quick and easy to press without looking down at the keyboard. Take your pick  :)
