Middle button scrolling not working (TrackPoint)

tejohnso commented 3 years ago

Sway Version:
- 1.6.1
Debug Log:
- https://pastebin.com/Ad4yQ6F0
Configuration File:
- default configuration https://pastebin.com/Kj89edct
Description:
- Immediately upon starting sway, open a terminal and start Brave (or chromium) and navigate to news.google.com
- Hold down middle trackpoint button and move pointing stick
- Notice no scrolling is taking place in the browser
- In terminal, confirm libinput debug-events outputs numerous POINTER_SCROLL_CONTINUOUS events when scrolling
- In sway debug log, notice multiple "Unknown libinput event 406" entries

I believe this should be addressed by the in-progress https://github.com/swaywm/wlroots/pull/3082. I'm a little surprised the non-hi-res versions of the events are not sent, but I'm not very familiar with the matter.

I have noticed that, too, but for me at least it seems to be exclusively the case for Chromium (-based browsers). It works fine in all other windows.

Just see this issue as a mention in the high-resolution PR.

I'm a little surprised the non-hi-res versions of the events are not sent, but I'm not very familiar with the matter.

The kernel should be sending both low-resolution and high-resolution events. When the kernel doesn't support high-resolution (Linux < 5) libinput does the emulation. You are right, both events should be sent.

@tejohnso could you attach the output of sudo libinput record, please? You can redirect it to a file: sudo libinput record > record.txt.

The command will ask you to select your device number. Once selected, reproduce the issue by pressing the middle click button and moving the trackpoint. Then press Control+C to exit.

That'd help me to discard (or not) an issue in libinput and to the wlroots devs to replay it locally using libinput replay <file>.

I'd be helpful to know if it happens globally or, as @chmanie mentioned, only in Chromium.

I'm pretty sure this is a Chromium-only issue and specific to the Ozone cross-platform layer. I see this as well when running Vivaldi (Chrome 94) with --enable-features=UseOzonePlatform --ozone-platform=wayland. If I omit this flag (so that Chrome falls back to Xwayland) trackpad scroll works fine.

This was a fairly recent bug (~2 months) as I've been running with Ozone for a year or so and it has previously worked, I'm just not sure if it's Sway or more likely Chromium given it depends on the backend, and from my attempts to debug locally, the trackpoint axis events are generated fine.

Thanks @tokyovigilante

@JoseExposito I've confirmed that scroll does not work in Chromium, but does work in Firefox. And my record.txt output is similar to that of @tokyovigilante

JoseExposito commented 2 years ago

Thanks for the logs. I asked because there was a similar bug with a different trackpoint recently in libinput.... I can not help much with this one then :(
