            Bug ID: 219789
           Summary: [regression] Moving Logitech mouse causes WINE to lag
           Product: Drivers
           Version: 2.5
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: USB
          Assignee: drivers_usb@xxxxxxxxxxxxxxxxxxxxxx
          Reporter: esteve.varela@xxxxxxxxx
        Regression: No

I have a Logitech G502 Lightspeed mouse, set to 1000Hz polling rate. When
moving the mouse, wine lags. This didn't use to happen, which feels like a
regression.

This issue started happening when upgrading from 6.6.67 to 6.12.7. Downgrading
causes it to work again, and for good measure I've tested an unpatched version
of 6.13.2 with an exact copy of the 6.6.67 config (make olddefconfig && make).
All the results for 6.12.7 mentioned below have been re-verified with 6.13.2.

Since upgrading, moving the mouse around in any WINE application, including
games and other applications, will cause the application to become sluggish.
This happens exclusively with this mouse, as the laptop's touchpad and
trackpoint both function properly, as well as an old HP mouse that I had laying
around. I haven't tested any other input devices beyond those listed here, all
the devices tested had a sub-300Hz refresh rate.

To rule out a WINE regression, I've tested different versions of WINE:
wine-staging-9.22, wine-staging-9.0 and wine-vanilla-9.0. Only when I boot the
6.6.67 kernel is it resolved.

I've read that high polling rates can cause WINE applications to lag[1][2]. As
such, I wondered if the mouse's polling rate had changed across kernel
versions. To verify this, I used the evhz tool[3] on both working and
non-working kernel versions. Both 6.6.67 and 6.12.7 reported around 1000Hz for
this mouse. Using libratbag/piper to configure the mouse for a lower polling
rate did make a difference, but I had to lower it to 250Hz, as 500Hz caused
(more minor, but still apparent) stutters. This seems unreasonably low, given
the reports on the issue are always about rates higher than 1000Hz.

How to reproduce:
- Connect LG G502 mouse to computer using either the wireless dongle or USB
cable
- Download BGB (https://bgb.bircd.org/bgbw64.zip)
- Run the demo game in WINE (wine bgb64.exe bgbtest.gb)
- Move the mouse around, notice how the animation starts stuttering

As an anecdote, when testing a directx input latency meter for windows linked
on the arch wiki[4], I only occasionally get some 700-800Hz out of kernel
6.12.7, whereas with kernel 6.6.67, I easily get the 1000Hz. I assume this is
related to the stuttering as well.
