Description
The tst_qquicktextinput::cursorVisible() test is crashing when cleaning up one of two QQuickView objects created on the stack. The first view contains a TextInput, the second is empty and was simply used to steal focus from the first. The crash in the test has been addressed by changing the second view to a QWindow with http://codereview.qt-project.org/#change,22250
The backtrace suggests the destructor for QSGDefaultDistanceFieldGlyphCache is accessing an invalid shared gl context, presumably cleaned up while destroying the second view.
