Touch “overload” in Unreal Engine

[Asca]

Hi,

I’m developing a 3d application for a museum, which will be available on Windows and will require a touch screen, so I’m using your (great) software to simulate the touch screen with an android tablet.

But the problem is that touch inputs very quickly get stuck in Unreal, as if you never released your finger. This happens when you make quick inputs, and after a while it’s as if Spacedesk can’t keep up and can’t release the inputs. This makes navigation impossible because the software responds with one or two fingers and not with 3, 4 or 5. I’ve tested this with similar software and I’ve only encountered this problem with Spacedesk.

To reproduce the problem in Unreal you need to set up a project that uses touch inputs and then make quick inputs on the tablet screen, like the movement that an impatient person would make with their fingers, if you know what I mean, by quickly placing the fingers on the tablet one after the other.

Is there a solution to my problem? Or is it a bug that can be fixed in a future version?

Hi @Asca,

We will try to reproduce this on our side as well.
In the meantime, could you please tell us your setup when this issue occurs? and could you also verify if it is also happening outside of Unreal Engine when using spacedesk?

Hi Christian,
I’ve encountered this issue on two Windows 11 PCs and with two tablets : a Samsung Galaxy Tab S5e (SM-T720) on Android 11 and a Samsung Galaxy TabA 2018 (SM-T590) on Android 10. The Unreal Engine versions were 5.1 then 5.2.

I’ve just run a few tests and I haven’t managed to reproduce the problem on other software (Blender and Photoshop), or at least the softwares have continued to work correctly. It’s hard to say whether inputs remain blocked when you don’t have graphical feedback.

I can add that before coming to you I thought the problem was with Unreal but I haven’t found any problems similar to mine on the forums and no-one has been able to help me. And as I said before, I did a test with another software (Google Desktop remote) which was less efficient than yours but didn’t have this problem of blocked inputs.

Finally, I don’t know if you’re familiar with Unreal, so if you need help creating a touch project or if you want me to send you a ready-made project, don’t hesitate.

Hi @Asca,
Thank you very much for the information you provided.
We were able to reproduce a similar issue of a stuck mouse using Android viewer and are working on a solution.
We will keep you updated on the progress and let you know once a fix is available.
