Bug description

I use an XP-PEN Artist 15.6 and every of my plays get flagged with the touch device mod. But the version of my tablet has no touch capability's.
It doesn't matter if I select the beatmap with mouse or tablet the score still gets the mod.
To add to this I am not even a drag player I just hover over my tablet.

This shows if I drag or select anything with my tablet pen it applies the mod

Here I select the song with my mouse but it still applies the mod afterwards if I use my tablet in any extend

I just had this problem problem what I did to fix it was going into the Wacom drivers and change the settings to where when you touch the pen down to the tablet it doesn’t count as a click like for a mouse and that fix the problem for me

New to using github so I hope this is alright, but I'm having the exact same issue with my old "Huion H420".

I do not use the original Wacom driver because they led to problems with my system. That is why I use OpenTabletDriver.

I would have another suggestion for the solution of the problem. I usually play without klick input in osu!standard if that is active it should be irrelevant if I use a "Touch Device" or is it?

Second this. CTL-472 detected as a touch device, using OpenTabletDriver with Wacom drivers disabled, Tablet mode disabled in-game. Attempting to disable Touch mode in-game makes every input be detected as a 'click' or 'drag' which makes the game unplayable.

It looks like some part of #25348 is not working as intended.

No it's most likely either an upstream bug in SDL or the tablets involved are reporting weird events which get mistaken by SDL / input layer to be touches. I can't say for sure because I own none of the hardware. But at this point we're probably going to have to port the stable heuristic algorithm across instead because obviously there are too many complaints that the touch detection does not work exactly like stable.

[Coocys]

Is there any way we can help to fix this? Because obviously we own the devices that led to the problem and could provide any info you need.

[bdach]

If you are able, you could try running the game with the SDL_EVENT_LOGGING=1 environment variable set, then click around to trigger the touch input detection, and then attach runtime.log from that execution. That could confirm what the device is reporting. Unless the in-game opentabletdriver interferes.

You could try messing with that too actually I guess. See if disabling/enabling in-game OTD fixes this or not.

But none of that changes the fact we're probably porting stable's detection across anyway, as people are complaining that players that use touchscreens in ways that technically do not make the game easier are getting unfairly nerfed by touch detection relying on the hardware reports.

I still tested around with the build in OTD.
It fixed it for me that means when I turn of the OTD on my pc and use the build in OTD the mod does not get applied.

If I find the time I try to log it with the OTD from my pc. But I am not sure how long that will take due to time and knowledge how env variable works and how I run osu with it.

Known issue with windows ink: #5378 (comment).
A fix is pending in ppy/osu-framework#5309, but it requires a change that has been merged to SDL3, but not SDL2. I guess we could change to use our fork of SDL2 again, or just do a one-off build with the change cherry-picked.

Might be best to backport ourselves if SDL are not going to.
