Unwanted lines in jit.lcd

Trying to create a square that continuously gets smaller and will loop, but upon resetting a vertical and horizontal line along the middle appear
not only horizontal.

no idea why this happens, but i would get rid of that unnecessary dual-metro, dual-counter design, then you have better control over when "clear" is performed.
and it could also be a good idea to use float values for the size. the interpolation looks slightly different between mac os and windows but if this is an mask or alpha channel you will probably work with it as char anyway (and not 2-bit)
Use pack i i i i instead of pak, and it should work as expected :-)
(with pak, framerect is drawn 4 times for each bang...)
there we go.
