No

InputActions from Mouse are sometimes skipped

Package: Input System

-

The original bug was for Android, but after testing on Editor, I think something's wrong with input actions themselves

Repro steps:

  • First take a look at video attached below, it was taken with Unity 2020.3.26, input system package 1.2.0 in Editor on Dell Laptop with Touch Screen monitor

- I am first drawing with mouse, and the drawing lines are supper jaggy, seems like half of input actions events from mouse are not coming through
- Then drawing with touching the screen, even though laggy, the drawing is much more smoother
- Again drawing with mouse, it seems like no input actions are coming through for the first 2-3 seconds, then the drawing starts appearing again, but lines are supper jaggy

  • Open case_1339170-DrawReproSmall.zip (It's a trimmed down repro with Debug.Log entries removed, the original one was 500 MB and had Debug.Log)
  • Run in Unity 2020.3, preferably on a PC with touch screen monitor hooked, so you can compare touch versus mouse drawing
  • Launch the scene in editor
  • Draw with mouse
  • Draw with touch
  • Drawing with mouse looks horrible, looks like half of the input actions are simply not coming through

Expected: Input is drawn correctly
Actual: Input isn't drawn correctly

BELOW STEPS are for Android, leaving it for references.

Repro steps:
1. Open attached project 'DrawRepro'
2. Build and Run to an Android device with a stylus
3. Draw on the screen alternating between fingers and stylus

Expected: Input is drawn correctly
Actual: Input isn't drawn correctly

Reproducible with: 2020.3.13f1 - Input System 1.0.2, 2021.1.14f1 - Input System 1.0.2,
2021.2.0b2 - Input System 1.1.0-pre.5, 2022.1.0a1 - Input System 1.1.0-pre.5

Couldn't test 2018.4 and 2019.4 due to not being able to build the project

Tested and reproduced on these devices:
VLNQA00316, Samsung Galaxy Note10 (SM-N970F), Android 9, CPU: Exynos 9 Series 9825, GPU: Mali-G76

  1. Resolution Note:

    No longer reproduces in Input System 1.4.1+

  2. Resolution Note (1.3.X):

    No longer reproduces in Input System 1.4.1+

    Brief update, but I have revisited this item using Unity version 2020.3.24 with version 1.2.0 of the input system and it is still occurring.
