Description

Hello, 

we are using Guacamole Client on Notebooks and Tablets with Touch-Screens. 

Since version 1.4.0 we spotted issues while clicking over touch screens when zoomed in a little bit. Its causing the screen to move the content instead of performing the click. 

You can only reproduce it with real touch screen events (simulating touch over developer tools in chrome will not cause the issue). Its happening on all devices doesnt matter if notebooks or tablets connected to a RDP session.

• Open a connection and click on some positions, which will work as long as you dont zoom in
• Zoom a little bit in and then try to click on certain positions -> sometimes it will click there sometimes it just moves the screen.

See attached GIF.
In version 1.3.0 its not happening at all.
