Fix support for Lizard Mode

[ayufan]

Tries to resolve: #215

[ayufan]

@General4878 can you test this?

[General4878]

I will when I get home in a couple hours. Excited to see if it works!!

[General4878]

@ayufan built it and the problem still happens unfortunately 🙃

[ayufan]

Give me exact steps and configs when it happens, etc.

@ayufan

go into the scripts folder and run batch file
go into build-Release folder and run SteamController.exe
use Xbox360 mode in setup controller
SDT starts with lizard mouse/ buttons by default so no problem happens.
right click steam controller tray icon and open settings
set Lizard Mouse to true
cursor starts pausing and resuming again every 1/4 second
enable lizard buttons as well, cursor jumping stops.

Tested with steam running/not running in the background, same result.

The symptoms are the same as with the old build

do you need anything else?

[General4878]

@ayufan i see you are disabling watchdog only when lizard mouse is disabled, maybe it should always be disabled no matter the configuration of lizard mouse/buttons?

[ayufan]

Probably. Can you check this? I don’t have steam deck, so I just repurposed kernel change.

@ayufan Just did. No matter if watchdog is disabled in every situation, the problem still persists.

interestingly I found that if LizardButtons is enabled but LizardMouse is disabled in the SDT settings, Lizard Mouse stays enabled and it doesn’t stutter.

@General4878

Would you mind filling this table, or whatever columns are suitable? This would help me better understand behavior, and see what I can do:

Lizard Buttons	Lizard Mouse	Steam Deck Mode	Expected Mouse Behavior	Expected Keys Behavior	Observed Mouse Behavior	Observed Keys Behavior
Yes	Yes	Steam Input
Yes	No
No	Yes
No	No
Yes	Yes	X360
Yes	No
No	Yes
No	No

[General4878]

@ayufan I will have to fill in the table tomorrow as I need to log off.

But another piece of information I found which is very important:

  if (savedLizardButtons == LizardButtons)
  {
      // We need to explicitly disable lizard every some time
      // but don't fight enabling it, as someone else might be taking control (Steam?)
      //if (lizardButtonUpdated.AddMilliseconds(LizardModeUpdateInterval) > DateTime.Now)
          return;
  }

I commented out the time check for the UpdateLizardButtons method, meaning the report is only sent when the LizardButtons setting is changed instead of every 250ms. And the mouse stops stuttering... It only seems to stutter when i disable LizardButtons.

So I think the mouse stutter happens every time we send this report:

SendFeatureByte(ID_CLEAR_DIGITAL_MAPPINGS);

[ayufan]

Interesting. We can try this as well.

@ayufan I have tried it already, but problem is that we don’t just need to disable LizardButtons once, we need to do it every some time because steam enables it again.

But every time we send ID_CLEAR_DIGITAL_MAPPINGS, it causes the mouse movement to stop, so we cannot do it constantly.

Maybe there are other feature reports we can send to disable LizardButtons without sending ID_CLEAR_DIGITAL_MAPPINGS?

[ayufan]

The problem because steam enables it again is problematic. We likely have to hide this from Steam.

@ayufan

Lizard Buttons	Lizard Mouse	Steam Deck Mode	Expected Mouse Behavior	Expected Keys Behavior	Observed Mouse Behavior	Observed Keys Behavior
Yes	Yes	Steam Input	Glide normally	Register keys	As expected	As expected
Yes	No		SDT mouse emulation	Register keys	Mouse glides	As expected
No	Yes		Mouse glides	Buttons emulated by SDT	Mouse stutters	As expected
No	No		Mouse emulated by SDT	Buttons emulated by SDT	As expected	As expected
Yes	Yes	X360	Mouse glides	Buttons registered	As expected	Double presses as Emulated and Lizard both called
Yes	No		SDT mouse emulation	Buttons registered	As expected	Double presses as Emulated and Lizard both called
No	Yes		Mouse glide	Buttons registered	As expected	Mouse stutters
No	No		SDT mouse emulation	Buttons registered	As expected	as expected

As per my previous comment, everything works as it should except when disabling LizardButtons with ID_CLEAR_DIGITAL_MAPPINGS which causes mouse stutter when LizardMouse is enabled.

And when LizardButtons is enabled, but LizardMouse is disabled in settings, the mouse glide doesn’t seem to stop.

All the problems seems to happen in the method made to change LizardButtons
