On my dev machine my plots work great, but when I deploy it to another PC unusual things happen

1- no plot data is displayed
2- divider lines do not display
3- the time coordinates on the bottom advance across the screen one plot width at a time, leaving a trail of time units behind
4- screen resize clears the trail, until next plot interval

I am using OpenGL and thinking this may be part of the problem.
line width is set to 3

Both PCs are Windows10, and the deploy tester is a 2012 vintage Vaio, while the dev machine is a newer Alienware.

I have tried several versions of openGL dlls but no luck.

Are there QCustomPlot DLL's that need to be included in my deploy?
Any other ideas?

Thanks

Rick
