I have been using Tango fine with Qt 5.10. I am guessing this is related to the old version of Qt.

I'm on Trusty as well, and I compiled master & lib-redesign with qt5.2.
There are various crashers appearantly related to waveforms and other paint events.

It crashes when the library is sibling with spinnies. This leads to a size change during painting which invalidated the QPaintDevice and leads to the crash:
QPaintDevice: Cannot destroy paint device that is being painted"

The style is unrelated.

Not sure what is special with the spinnies in tango that it only crashes here.
Anyway, the bug can be fixed if we remove the temporary button, used for painting all preview buttons, from the QT Object tree. I have used a std::unique_ptr instead.

What does that mean?

I suppose you want to link to #1747

If I remove the library, no crash.
If I remove the spinnies, no ctash.
If I parent the render button to a the menu bar, no crash.
Since the button dies not inherit style from a parent, no parent is the cleanest solution.

fine, if it's fixed.
I compiled 2.1 with qt5.2 and removed the spinny templates.
It crashed when I opened the Skin Settings.
Removed the library (main table, tree is there) as well, and it didn't crash.
Deere also crashed on various occasions until I removed the lib table.
