Default Switching GPU?

Thank you so much Frank,

This is a high quality bug report!

It looks like this flash happens when Mac OS is switching GPU. And it's doing so when certain applications are opened, probably because they are linking frameworks that can benefit from the faster GPU.
If this is true this issue should only be visible on the new 15" and 17" MPB.

The symptom is not too bad luckily. The only hint in your logs is a WindowServer error, which is compatible with the fact that you're not seeing any kernel panic. And that the flash is on all screens. We'll start from there. And from getting a new MBP :-)

I have to warn you that we are working on other issues and improvements so I can't commit on a date for a fix.
