Right debugger pane stays hidden until resize

Steps to reproduce:

1. Open Qt Creator in full screen mode (maximize), the width in full screen must be less than without it (the case with my vertical display)
2. Open any project/create a simple widgets project
3. Start debugging
4. Switch to the Edit view
5. Close the app
6. Start debugging again

Result: Debug view is activated but the right pane is not shown.

There's a workaround to un-maximize the Qt Creator windows and maximize again but that's quite annoying.
