Summary0025713: UWP: Keyboard handling for UWP desktop results in severe input lag
DescriptionI noticed that when running my game in the UWP export variant, there is a noticeable lag for keyboard input. This issue is also reproducible on the "YoYo Platform" example shipped with GMS 2.0

To be sure this isn't some issue with my own system I tried the following:
- The "old" windows .exe export works fine
- Downloading some random platformer games from the windows 10 store also behave fine.

This makes me conclude it is something related to the GMS UWP module, and not my hardware

Please note that this problem exists in both GMS 2.0 and GMS 1.4.

Unfortunately, this issue makes my game unplayable for standard keyboard input. I consider this a "showstopper" as a result.
Steps To Reproduce How to reproduce:
- Run the "YoYo Platform" example in the UWP desktop export
- Quickly alternate between walking left/right, after a few seconds the lag becomes very visible. It is even possible that the player keeps moving in the opposite direction of the pressed arrow-key. jump commands are no longer registered or very late, etc.
