2. Start electron client demo
3. Inject dota2
4. Currently, overlay UI is shown correctly
5. Change dota2 to different vedio mode, says, from windowd to exlusive fullscreen.
6. The renderring frame is freezed. (in other games, sush as Pummel Party, the renderring frame is not freezed, but the overlay UI is not shown in game.)

renderring frame is not freezed and overlay UI is still show above the game in step 6.
