I'm having an issue at 2560x1440 where occasionally a line of text will not be shown due to there being no room left in the box. I'll send you that file momentarily.
I just send you an email (I'm assuming you just send me the test.zip). I'm looking to fix it of course but another work-around (besides what I mention in the email might be to change config.txt (in install folder where taxinaut.exe is) from:
uiscale=auto
To
uiscale=no
It should give you a smaller screen of 1920x1080 centered on your 2560x1440. I know this is not what we want but as a temporary work-around it might suit.
