Synergy-core: Mouse cursor drifting upwards

Created on 21 Apr 2016 · 28Comments · Source: symless/synergy-core

Surface Pro 3 running Windows 10 as the server.
Ubuntu 15.10 as the client.

Whenever the mouse cursor is on the client (Ubuntu) screen, wiggling it side to side also causes it to drift upwards. There's also a noticeable "resistance" when trying to move the mouse downwards.

Are you using high DPI on your Windows server?

Surface pro is a high resolution display....?

Seeing this with win 10 on a 4k monitor with 1.5x scaling and the same model 4k monitor attached to a rMBP. Pretty much unusable. Larger mouse movements seem to work better, but things like selecting text are a real pain.

Seeing this with a Mac 10.12 server and WIN 10 client. The drift only occurs (for me) when the mouse is on the WIN 10 display.

Notes:

iMac is 5K.
WIN 10 is standard definition (1080 resolution).
WIN 10 has Razer Synapse.

Could you test this nightly please? This nightly includes high DPI fixes for Windows server.

Glad this is gaining traction. Any chance MacOS 10.12 Server suffers from the same issue?

I tried updating to the nightly on both my MacOS 10.12 server and WIN 10 client but it doesn't appear to have fixed anything.

@NaderCHASER
Thanks for your feedback. I have prioritized this ticket.

I've just upgraded from MacOS 10.11 (El Capitan) to 10.12 (Sierra) on the server and still using Windows 7 on the client.

Prior to the upgrade to 10.12 all worked OK; there was no drift upward. Nothing has changed on the Windows PC (no drivers, service packs etc)

Since installing 10.12 the drift has started and, as above, is rendering Synergy unusable.

I've tried synergy-v1.8.7-stable-9799e96-MacOSX-x86_64 and the nightly synergy-v1.8.8-rc1-4b913b5-MacOSX-x86_64 with their matching Windows releases, but both display the same problem. I'm not sure if it's me but it might be slightly less intense on 1.8.8.

I've tried with and without SSL but it happens either way. If you want me to test a build I'd be happy to help.

Just upgraded to 10.12 server and have a 10.11 client, and am now seeing this :(

I've just tried with:

synergy-master-stable-c5b83ce-Windows-x64.msi (client - Windows 7 x64 SP1)
synergy-master-stable-c5b83ce-MacOSX-x86_64.dmg (server - MacOS Sierra 10.12.3)

The drift problem still exists. I've noticed that the mouse is drifting up and left, not just up.

aminor00 on 22 Feb 2017

I have just tried a test with 1.8.8-stable-c30301e on the Windows 7 machine but this time acting as the server.
The client is now the MacOSX 10.12.3 Sierra box running the same level of software: 1.8.8-stable-c30301e.

With this configuration there is NO mouse movement problem, the mouse moves the way it should on both machines.

Switching back to the Mac being the server with the Windows 7 box as the client and the mouse movement issue comes straight back on the Windows 7 machine.

Unfortunately I cannot personally work this way around due to space and machine placement constraints. Therefore Synergy remains unusable for me.

Maybe this info will help someone else.

This issue has also been raised in #5607

Having the same issues here. Was running fine with Synergy 1.8.6 on a 5K iMac (server) and a MacBook (client), with the iMac on El Capitan. As soon as I upgraded to Sierra on the iMac I'm having this issue... wish I could go back now. Synergy 1.8.8 doesn't fix it for me.

In addition to the exaggerated up+left movement, my tilt wheel is inverted when used on the client computer. Both computers are iMacs, both set to use standard ("unnatural") scrolling.

I put on windows 10 via bootcamp and installed synergy and set it up as the server and my other macbook pro as client and the problem went away. It seems this is an issue with using Sierra as server.

rbalhorn on 24 Mar 2017

This appears to be the same problem as listed in #5648

The file synergy-v1.8.8-pr-5648-stable-1c1067d-MacOSX-x86_64.dmg.zip provided by PutzWorks in that thread fixes the mouse cursor drift issue for me (Mac 10.12 server with Win7 client).

I was using version 1.8.8 before I made my last report... so unfortunately, this version doesn't fix it for everyone.

stingray88 on 10 Apr 2017

@stingray88 Have you tried this specific version of 1.8.8? It has code changes in it to resolve the issue reported in #5648 and is therefore different from the official 1.8.8 release.

aminor00 on 10 Apr 2017

Ah my bad... didn't realize it was different. First impression, it might have fixed the issue! Thanks!

@robeberhardt Thanks for the heads up. @XinyuHou This appears to be fixed.

Only needed to update Mac server, not Windows client.

NaderCHASER on 10 Apr 2017

Fixes the issue on my iMac to iMac setup too. Thanks for the links!

iaian7 on 22 Apr 2017

Using Razer Synapse drivers, if I reduce the polling rate from 1000Hz to 125Hz, the up-and-left issue goes away.

MacOS 10.14 + Windows 10
Mac Server Windows Client

Moving mouse up and down slowly drifts the cursor upwards on windows 10 client

Same issue when using 1.10.1. Goes away if I use the 1.8.8 build linked by robeberhardt.

The fix is in master but for some reason the builds do not include it which is frustrating since it means I'm stuck on 1.8.8.

mejran on 23 Nov 2018

Also having this issue with 1.10.1, sadly the 1.0.8 binaries are no longer available ...

Err, found the following binary and it solves the issue:

antevens on 7 Jan 2019

Are there any problems, license related, that the fix which is included in the linked Version 1.8.8 did not make it into the most recent version?

Better asked, what is the problem that the fix does not make it in the current version and/or is it because the code moved on in a technical way that the code which fixed the problem in that linked version, does not work anymore in the expected way?

Linking all current active Project Maintainers to this to raise attention. As most of paying users may not be able to use Synergy with the most recent version within a macosx environment because of this bug.
