Unfortunately, the issue is not finding the offensive line of code, I have the most basic skills and it was pretty easy, just look for the table with the fixed size in it.
The issue is as they have made clear in this thread, they don't see any reason why it's a problem, because nobody is actually running a screen that small, and we all must be using etch a sketch machines if we are having issues.
Whoever put it in could easily fix it, and I would guess over time the complaints will drop off as it's just too tiresome to have to scroll back and forth for each and every line in a post, so more people will just give up and go away.
