Description
Found strange bug when call QFileDialog on Linux Mint 19.1 ( GTK ) when QGLWidget is active on main application.
apart of " GtkDialog mapped without a transient parent. This is discouraged."
FileDialog initially displays itself correctly but functionality of it is limited as refreshing of it is bugged.
Using GDB i found the loop is locked in this place inside qopenglfunctions.h
on Q_ASSERTS.
inline void QOpenGLFunctions::glClearColor(GLclampf red, GLclampf green, GLclampf blue, GLclampf alpha)
{
#if defined(QT_OPENGL_ES_2) && defined(Q_OS_ANDROID)
::glClearColor(red, green, blue, alpha);
#else
Q_ASSERT(QOpenGLFunctions::isInitialized(d_ptr));
d_ptr->f.ClearColor(red, green, blue, alpha);
#endif
Q_OPENGL_FUNCTIONS_DEBUG
}
As I said its only messing up refreshing filedialog still works when clicked even on masked place it will pass file location.
I noticed when I froze by GDB execution and restore again then once this window is redrawn.
I recompiled it on Windows no problem there.
