What's the problem? Describe what went wrong.

If the emulated pointer is set to use gyro inputs, the pointer will start bobbing up and down after about 10 mins of play.

What steps will reproduce the problem?

  1. Use a controller with gyro capabilities
  2. Configure a DSU server for the controller and set Dolphin up as a DSU client
  3. Configure the motion controls for your controller and enable the pointer option under the "Motion Input" tab
  4. Play a game for roughly 10 minutes and check the state of the emulated pointer
  5. The pointer should now be bobbing up and down without user input, gets worse the longer you play

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Yes, 5.0-11898

Is the issue present in the latest stable version?

No (DSU client feature is not available in stable)

What are your PC specifications? (CPU, GPU, Operating System, more)

Windows 10
Ryzen 2400G
16 GB DDR4 3000 MHz
Radeon RX 570

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

This is an issue with Dolphin and not the DSU server as disabling the DSU client in Dolphin, then re-enabling it will cause the issue to be temporarily fixed. I am using Steam Gyro For Cemuhook with GloSC for my Steam Controller. I also have a friend that has the exact same issue using BetterJoyForCemu for his Joycons.

What does the "Gyroscope" mapping indicator look like when the issue occurs?

#2 Updated by camperboy1000 12 months ago

Here is a 10 second clip of the gyroscope. The left graph is the change in angle as seen by the DSU server, the center is the pointer in game, and the right is dolphin's motion input tab.

Does using the "Recenter" button alleviate the issue at all, even if temporarily?
Or how about reconnecting the emulated remote? Alt+F5, Alt+F5

#4 Updated by camperboy1000 12 months ago

Using the "Recenter" button just recenters the pointer to the middle of the screen, the bobbing continues until the DSU client is toggled off and then on. It could also be that the more the controller moves, the worse it gets however I haven't been able to determine if that is absolute.

#5 Updated by Billiard26 9 months ago

Please reproduce the issue and then clear out your raw accelerometer mappings.
Does this stop the bobbing?

Can you please see if Dolphin 5.0-12873 or later fixes your issue?
