That sounds like something (possibly another app) might be interfering, in general there is still close to zero delay on macOS Sonoma.
You have configured this here, correct?
I can say that if I use this feature almost continuously, it responds faster, but when I try it without using it for 10-20 seconds, I experience a lot of delay.
interesting. Synergy needs to integrate in similar ways as BTT does, maybe that's causing issues. However I haven't heard of specific problems with synergy in the past :-/ Maybe it's a specific version of synergy?
There is still a delay from time to time, maybe it is not related to Synergy or there are other factors. However, it still works better when Synergy is turned off.
I found another interesting thing: if I try it from the top of the windows rather than from the bottom, the result is always like this. I get the same result in Finder and Safari
OK, I found a few things, I'm adding screenshots. I use a lot of "Floating Webviews". Once I open and hide them, "move/resize" does not work in these areas.
This explains why it works fine when I reboot.
I'm also attaching a sample "floating webview" screenshot. Is there a setting I can make to prevent this?
I created a new "float webview". If I select the "stick to desktop" option, move/resize does not work in that area, even though the float webview remains behind.
