[Interest] Crash in QXcbScreen::updateRefreshRate

[Scott Aron Bloom]

One of my customers is having a problem with our tool since we moved to Qt5.5.1.  We are not able to move to Qt5.6

They are running their system via exceed turboX

However, when the tool starts up, it is crashing immediately with the following call stack.

Any ideas for a work around?

Program received signal SIGFPE, Arithmetic exception.
