Jumping Mousewheel and no Double Click MacOS Client

[tobiashugo]

Using a Windows 11 (newest updates) as server and MacOS client (15.6.1) double clicks on the MacOS client are not recognized.
The scroll wheel jumps several lines instead of one.

I didn't find these issues, but am a GitHub noob, please delete/ignore if this post is irrelevant.

Best regards,

Could you clarify what you mean by server and client? I'm assuming, you are using the Win11 device to control your mac, is that correct?

[tobiashugo]

That is correct. If I can provide any more info or debug logs etc. let me know.

The software otherwise feels great, no menu popup on long right mouse button presses. That bug is bothering me with every other solution I've tried so far (barrier and forks, synergy 3, sharemouse and few others). No mouse cursor lags, no mouse pointer appearing in the middle of the client screen.

[feschber]

I will see if I can reproduce it!

In case you haven't, you may want to try deskflow as well :)

@nbolton, do you know about that long right button press issue?

@nbolton, do you know about that long right button press issue?

That bug is long standing since I first started using Sharemouse several years ago and has been consistent for me for all iterations of KVM Software. Synergy and Sharemouse support shrugged and couldn't provide a solution. Not having that behavior is new to me.
The reason I started looking for a different solution (tried deskflow as well) is, that all of a sudden the cursor jumps to the center of the mac screen when switching to the client in normal speed and not very slowly. Probably introduced by some mac or windows updates, as it now happens with all synergy 1/barrier forks and also synergy 3, yet not lan-mouse.

Would you mind opening a bug report in Deskflow if it happens there?

It doesn't ring a bell, but it sounds like @tobiashugo has been pretty thorough in their testing.

Synergy [...] support shrugged

Oh dear, would you be against sharing the support ticket number so I can dig a bit deeper? The more info I have the more I can understand the issue.

Now this one does ring a bell. This may be a bit off-topic but I don't suppose you have a Deskflow issue link?

yet not lan-mouse

Very interesting. I haven't yet made time to dig into the LAN Mouse source code for macOS, but I'm guessing newer/different API functions are used. Some of Synergy/Deskflow (and likely Synergy forks/clones) uses older deprecated functions which code needs modernizing.

@feschber Do you have any knowledge [roughly] of what macOS API functions LAN Mouse uses that Synergy/Deskflow doesn't?

[feschber]

@nbolton lan-mouse uses CGEventPost with cghidEventTap: https://github.com/feschber/lan-mouse/blob/main/input-emulation/src/macos.rs

Ah, same: https://github.com/deskflow/deskflow/blob/c91b2803972a4d913d99245f745cb1f2f4702574/src/lib/platform/OSXKeyState.cpp#L587

[feschber]

From the description, it sounds like the mouse jumping to the center of the screen could be caused by input-emulation code not waiting for the capture to warp the cursor back to its release position, causing the emulation code to offset from the captured point (which I'm guessing is in the middle of the screen?) instead of the barrier. This would at least explain why slow mouse movement would not trigger the issue. Just a guess though.

In LanMouse this does not happen because the cursor is currently not warped at all on input capture begin / end.

#337 should fix the scrolling. The double click problem is a bit more complicated, apparently on MacOS, a flag must be manually set for a double click to be registered.

I also noticed that for some reason control+up arrow does not seem to trigger the overview Window. I will investigate that as well.

[feschber]

#338 should fix the double clicking :)

[tobiashugo]

I can confirm both issues have been remedied BUT now the bloody right mouse button menu pops up after long click :(
This was introduced with #338, #337 was fine
I'd rather loose double click again and not have that popup. Left press and return is more convenient for me.
Fortunately Trash bin kept the #337 binary :)

@tobiashugo could you elaborate a bit more what menu you mean and when exactly it happens? I can't seem to replicate this.
Do you have any other software installed that may be interfering?
