From: Hawking Zhang <hawking.zh...@amd.com>
v2:
fix ddx build warning unused var
The change supports the following scenario when freesync enabled for steam game
1). use Alt+Tab to run-time switch between windowed mode and fullscreen mode
2). use option setting to switch between windowed mode and fullscreen mode
Also verified on unigine heaven via setting check/un-check fullscreen
