going from 10.12.3 to 10.12.4 introduced issues - scrambled popup windows

Here is a datapoint that might help others:

2014 rMBP with discrete video card will cause the scrambled screen issue 100% of the time when the discrete video card is being used. I can monitor this in the energy section of activity monitor. Launching certain applications requires "High Perf GPU".

I can also replicate the issue 100% of the time when I disable "automatic graphic switching".

Co-workers with 2015 rMBP is able to use discrete video card without any issues. Other users with 2015 rMBP and no discrete video card never experience the issue.

Hope this helps others...
