[yocto] [meta-qt5] How to bisect problem?

[Neuer User]

Hi

I was using qt5 5.3.0-beta1 for a long time. Now I upgraded to 5.3.2,
which is the current master.

Now I am experiencing some video problems. I reverted back to my old
5.3.0-beta 1 and the problems are gone. So, it seems one (or more)
commits between 5.3.0-beta1 and 5.3.2 are the cause of the faulty video.

How can I bisect this best to find the culprit? It doesn't seem to make
sense to just use git-bisect as not all versions will compile fine. Are
there specific points, such as 5.3.0, 5.3.1 that I should test? Or does
it make more sense to use some 5.4.0 beta version?

Thanks

Michael
