When using Guacamole to connect to a Windows RDP server, using Google Chrome,
on a computer with a HiDPI screen (3200x1800, 200% scaling), some artifacts
appear, as shown in accompanying screenshots.
Screenshots show an application (Notepad - but other apps show this problem)
with either horizontal or vertical 1-pixel lines between areas where the screen
On the first screenshot, the mouse cursor was moved vertically, causing
different menu entries to be selected, causing the horizontal lines. On the
