In playing with framebuffer drawing efforts, something interesting came up.
In brief (so as not to bore everyone) the same draw program and unit works differently between fpc and gpc. But neither work.
I suspect it is in the rewrite and/or blockwrite functions. I'm using 16bit pixels so I'm dealing with converting 16 bit to byte writes.
Anyway, for a simple red horizontal line on a solid background. Fpc gives me two red lines on a clean blue background. While gpc gives me a single red line on a spotted blue background.
Also, gpc gave me the proper error code for using blockwrite on a typed file.
Conclusion; a bad program performs differently on fpc and gpc.
