What happened?

I use the MX Master 3 mouse, and the forward and back buttons do not work for switching workspaces while Logi Options+ is installed. I found issue #4554, which was closed. However, it does not seem that that issue was completely related, as even the most recent comment still mentions that Logi Options+ is still causing issues. So, I thought I would open a new issue to get further clarification, as this is really messing with my workflow. Plus, I cannot uninstall Logi Options+, as that would make my mouse unusable for what I need. Thanks!

Just for some clarification:

• MX Master 3 buttons work fine if Logi Options+ is uninstalled, it's just when it's installed
• Having Logi Options+ installed does not prevent the issue on other mice. I tried my Logitech G502, and it worked fine. It's only my MX Master 3 (and probably other mice that run through Logi Options+) that have the issue
• zen.workspaces.scroll-modifier-key is currently set to control, but this does not work with this mouse either. Works fine with my G502.

If there's anything else I can provide, please let me know!

Using better-mouse instead logitech malware fixed this for me, you can also add the same gesture controls as in logi options (switching desktops, mission control, etc)

One workaround is to switch in Logi Options+ the behaviour of the thumb wheel. You can set it at "Switch between pages" in the "Other actions" list. For me this keeps both the horizontal scrolling functionality and makes Zen understand the workspace switches.

I'd rather not do it, but at least it's workable for now.

I am giving this a try; thanks for the suggestion! It's working well so far; the only problem is that I don't see an option to adjust the zoom in and out sensitivity like I can in Logi Options+, so that's throwing me off since I use that feature quite a bit. But I'll continue using this for now to see if I can get used to it. Still hoping that Logi Options+ gets compatibility, though

I was using this before but I just couldn't get used to it haha. I'm now trying out better-mouse as per @diegodsg's suggestion.

But I will say had that not worked for me, I don't think I would have been able to make the switch from Arc, so glad that there is at least some kind of workaround for Logi Options+ users, even if it's not the best currently

I am using my thumb mouse wheel to switch workspaces.

It took me a bit to get used to it too. I wonder if there’s a way we could help figure out how BetterMouse captures the side buttons and gestures—maybe if we can intercept the events triggered by the Logi software, we could come up with a proper solution for this issue. If Arc devs could figure this out I bet we can too 🦾

So far I tried with Karabiner event viewer but the side buttons won't log any event when logi options is running...

Same with an MX Vertical (which does not have a side wheel, so no workaround).

Also, same issue with BetterMouse, when the buttons are remapped to "Swipe Back" and "Swipe Forward" (which I think should be also the cause in Logi+).

And even with the trackpad, compared to Arc, the scroll between workspaces ask for way more movements, so maybe it's the way it's originally implemented that is an issue (no via back/forward gestures, but via scroll):

This should be handled around:

desktop/src/zen/workspaces/ZenWorkspaces.mjs

Lines 411 to 419 in dd005b3

	attachGestureHandlers(element) {
	element.addEventListener('MozSwipeGestureMayStart', this._handleSwipeMayStart.bind(this), true);
	element.addEventListener('MozSwipeGestureStart', this._handleSwipeStart.bind(this), true);
	element.addEventListener('MozSwipeGestureUpdate', this._handleSwipeUpdate.bind(this), true);
	// Use MozSwipeGesture instead of MozSwipeGestureEnd because MozSwipeGestureEnd is fired after animation ends,
	// while MozSwipeGesture is fired immediately after swipe ends.
	element.addEventListener('MozSwipeGesture', this._handleSwipeEnd.bind(this), true);
	}

I'll try to setup the project locally to debug what happens with our mouses, and open a PR.

EDIT: Posting my findings here in live:

• Before enabling Logi+ or BetterMouse, the events are AppCommand (Back and Forward) events, handled by

  desktop/src/zen/workspaces/ZenWorkspaces.mjs

  Lines 325 to 345 in dd005b3

  	_handleAppCommand(event) {
  	if (!this.workspaceEnabled || !this._hoveringSidebar) {
  	return;
  	}
  	const direction = this.naturalScroll ? -1 : 1;
  	// event is forward or back
  	switch (event.command) {
  	case 'Forward':
  	this.changeWorkspaceShortcut(1 * direction);
  	event.stopImmediatePropagation();
  	event.preventDefault();
  	break;
  	case 'Back':
  	this.changeWorkspaceShortcut(-1 * direction);
  	event.stopImmediatePropagation();
  	event.preventDefault();
  	break;
  	}
  	}

• After enabling them, the raised event is a MozSwipeGesture, but that is not happening after a MozSwipeGestureStart, so the handler doesn't handle it.
