Raw input fails to initialise correctly occasionally

[Addalt]

When starting the game with raw input initialised, there is a chance it will not work.

Note: this issue thread has been repurposed to track a more specific issue. for tablet related issues, see #3911

The same happens to me with a normal wireless mouse, but in a different way: when I launch osu!lazer with the raw input, the mouse works perfectly, but for no reason, it disconnects. When I reconnect it, your same problem happens, and I have to relaunch osu!lazer / disable Raw Input

What host operating system are you both on?

Windows 10 Home (64bit)

Similar issue here; on Manjaro (64x) and using a mouse; turning on raw input just keeps moving the cursor to the corners of the window

Same here, Manjaro (64x) with mouse

This is still being reported after switching to SDL2, so there must be something more to it.

Going to move this into the march milestone since it is still being actively reported. Would appreciate anyone that can reproduce this issue (and is able to debug it) to provide more details. Currently I'm not sure at all how this is happening.

It's kind of weird because sometimes raw input seems to work for me, but sometimes it doesn't (as you can see from the video below):

raw-input.mp4

Not sure how to 100% reproduce this but I noticed something strange when the raw input doesn't work (you can also see this from the video above):
If you manage to hover the Cursor sensitivity slider while raw input is in this "enabled-but-not-working" state (the best way is to unfocus the window and re-focus it on the slider), then change its value with the arrow keys, sometimes the game throws this error:

I've had this issue come up a few times for me aswell.

The steps below manage to reproduce it 90% of the time for me.

1. Start osu-lazer and enable rawinput and change to windowed mode.
2. Open up any unrelated window like file explorer etc
3. Restart osu-lazer.
4. Before the osu window appears grab and move around the other window, keep doing this until the menu appears.
   Video example :

Above was done in windowed and local debug but I've managed to reproduce with both fullscreen and master.

Windows 10

The whole window grabbing stuff is probably a bit excessive, I'm guessing you just need to have the osu-lazer window not be in focus on startup but this was the easiest way i could consistently reproduce it.

[frenzibyte]

Reproduced, will investigate through this and see if I can nail something down.

@frenzibyte this report was for a tablet. Can you confirm whether you are testing using tablet or mouse?

I've repurposed this issue to track the more specific case of OsuTK initialisation failure.

[frenzibyte]

Closing and unpinning as osuTK's "raw mouse input" handler has been removed osu!framework-side, leaving this issue stale as it should no longer be the case, with the alternative "high precision" mode which relies on SDL2's relative mouse input.

If it does really matter, this could be tracked at osuTK's repository side, but I don't think it should at all.
