I have two different applications (separate codbases) on the Mac that run on OS 9 and OS X and both applications are offseting the gl drawing area by one pixel horizontally and vertically when they are run under OS X. Under OS 9 they seem to run fine. Has anyone run into this problem. Is this an OS X bug, or could both applications be doing something wrong. Thanks for any information, I have not been able to find anything on apple’s website or here regarding this problem.
