On some occasions, osu!lazer starts with "Composed: Flip" present mode and doesn't switch to "Hardware: Independent Flip" in-game (despite FSO being disabled system-wide)

Bug description

When you start osu!lazer with DXGI API, there's a chance it will start and remain in "Composed: Flip" present mode. I couldn't find reproduction steps, it only happens after system boot-up, without previous attempts to run osu!lazer.

The main problem this issue causes is huge impact on input latency.

The issue can be mitigated for example, by re-initializing GPU via device manager. I think that changing graphics API doesn't fix the behavior, neither does restarting the game.

What does this mean? How are you starting the game?

All I meant was DirectX 11 in settings, my bad

First step forward here is to figure if anyone else can reproduce this.
