Amablue Posted June 18, 2017 Posted June 18, 2017 I tried posting this on the 'Crashing' section but didn't get a reply there... which I guess makes sense since it's not technically a crash, but it's still an issue I'd like to resolve. I have two Windows 10 computers. One is a laptop and one is a desktop. On my desk at home I have three monitors. The two on the right are my desktop's monitors. On the left I have an older spare monitor, and when I have my laptop at my desk with me I'll plug it into that monitor so my laptop can have dual screens instead of just the one. So my setup is a follows: [Laptop] [Laptop secondary monitor] [Desktop monitor 1] [Desktop monitor 2]. The laptop is the client and the desktop is the server. My laptop's screen is 2560x1440. My secondary monitor is 1680x1050. My Desktop's monitors are both 1920x1080 When I use Synergy and the laptop has no secondary screen attached it seems to work fine, at least so far. When I have the second monitor attached though, it gets a little bit buggy. Here are the reproduction steps: 1) Start with the cursor on Desktop Monitor 1. 2) Move left to the Laptop secondary monitor. Everything is fine so far. 3) Continue moving left to the laptop's built in screen. As you move leftward across the screen, the cursor will jump back to the laptop's secondary monitor. This jump occurs when you cross approximately a quarter of the screen, and the position it jumps to is about a third of the way from the left of the laptop secondary monitor. 4) If you continue moving left and make your way to the laptop's built in monitor everything is fine now. It can move around without issue. 5) Move the cursor back to the secondary monitor. As you cross vertical line where the cursor appeared when it jumped, it will jump again back to the laptop's monitor where it initially disappeared from To more clearly illustrate what I'm describing, I drew a little picture in MS paint of what's going on. Imagine I move my mouse to the left until I hit the far left edge of the screen, then start moving right to get back where I started. I graphed the x position of the on screen cursor over time showing where the jumps occur.
Amablue Posted July 25, 2017 Author Posted July 25, 2017 I just figured out what's happening. I figured I should post the cause of the issue in case someone else runs across it. Hopefully the developers can fix the issue. My laptop's main screen has a very high resolution but a physically small screen, and so it was set to scale the UI by 150% by default. Under Settings > System > Display there's a slider or drop down menu (seems to be different on some computers) that controls the UI scale labeled "Change the size of text, apps, and other items.". Setting back to 100% makes the cursor jumps go away entirely. It also makes all the start menu buttons tiny on this screen, but c'est la vie.
UkJung Kim Posted August 27, 2017 Posted August 27, 2017 I have same issue with it. I'm using 125% scaling FHD laptop and 100% scaling SXGA extended monitor.
Harris Teague Posted September 30, 2017 Posted September 30, 2017 same issue here. I'm using 150% on the windows laptop. This is important because I just can't use the laptop at 100%, though that does fix the synergy issue.
