Issues in 64 bit - 32 bit works fine

Targets macOS

I have some old code that works fine in 32 bit and compiles fine in 64 bit…but there are a number of issues with in 64 bit.

I have graphics that don’t draw, slow drags (over the invisible graphics) another issues… Don’t know where to look.

Here is a lonk to am MP4 file that shows what I am taking about. I first run the cdd in 32 bit mode in the IDE and then run the same code compiled in 64 bit.

Yes… Tons screaming about an invalid context like this one:

[quote]11/23/15 7:50:30.450 PM My Application[10110]: CGContextSaveGState: invalid context 0x6080001768c0. This is a serious error. This application, or a library it uses, is using an invalid context and is thereby contributing to an overall degradation of system stability and reliability. This notice is a courtesy: please fix this problem. It will become a fatal error in an upcoming update.

And it only happens in the 64 bit compile.

I’m on 10.9.5 BTW

I’m not using declares to draw.

Found the issue… it was code to determine the scale factor to detect retina displays (I don’t have a retina display)

Fixed it by changing a structure
