API:gfx.blit/gfx.drawstr disappears text/image, when gfx.y and/or gfx.x is too low

[Meo-Ada Mespotine]

When setting gfx.y too low, the text that shall be shown by gfx.drawstr disappears.

In the following code, the text isn't shown at all:

gfx.setfont(1, "Arial", 18, 0)
function main()
  gfx.x=1
  gfx.y=-18
  gfx.drawstr("BreadFan\nTudelu\nOhMyGod\n123\nOhNoMoreTests")
  reaper.defer(main)
end

main()

However, if I set gfx.y to -17, it is partially shown again, as I expect it to be.

I try to code a scrolling engine, where text might be scrolled out to the top, but this bug prevents me from doing it.

Edit:
gfx.x is also affected. Textlines not visible in the window get cut off. That means, if the first line isn't visible, the second line becomes the first line now, if visible.

gfx.setfont(1, "Arial", 18, 0)
function main()
  gfx.x=1
  gfx.y=1
  gfx.drawstr("1\n22\n333\n4444")
  reaper.defer(main)
end

main()

shows all lines, but changing gfx.x to -10 makes the 1 disappear, putting the line with 2 to the top.

It only happens, when using a different font than the standard system font.
Like Arial or Time New Roman.
