I find clicking through the tabs crashes qgc quite often now. I have also encountered same crash when changing params and saving param files.
Here are the errors that show up
(QGroundControl.exe:5768): GLib-ERROR **:gmem.c:103: failed to allocate 3110491 bytes
Microsoft Visual C++ Runtime Library
Program: C:\Program Files
not sure whats going on but its starting to be annoying
